+Noticeable Changes between PHP/FI 2.0 and PHP 3.0
+=================================================
+
+This file was designed to be viewed with a tab size of 4 characters.
+
+This file is divided into 4 sections:
+1.  Downwards incompatible language changes.  This section includes all of
+    the changes in the core language which may require people to modify
+    their scripts before using them with PHP 3.0.  It does NOT list
+    changes made in the behavior of specific functions.
+2.  New language features.  This section includes all of the new additions
+    to the core language, that may be used to enhance scripts designed for
+    PHP 3.0.  Likewise, it does not include a listing of new functions.
+3.  Structural changes not directly effecting the end user.  The core
+    of PHP 3.0 is a complete rewrite.  As such, many issues effecting
+    PHP/FI 2.0 were addressed and vastly improved in this version,
+    resulting in a much more stable and efficient implementation.  This
+    section lists these changes in design.
+4.  Other changes that don't fit in any of the above categories.
+
+Please remember that PHP 3.0's core is a complete rewrite, and thus,
+there may be other undocumented incompatibilities we haven't thought
+of ourselves.  If you think you've found a incompatibility (or a new
+feature) which is not listed here, please mail us at
+php-dev@php.iquest.net.

+
+Downwards incompatible language changes
+=======================================
+
+[1]	The close-PHP tag has changed from > to ?>
+
+	This means that instead of writing:
+
+	<?echo $title;>
+
+	You should write:
+
+	<?echo $title;?>
+
+	PHP3 also includes support for a longer-form start tag that is
+	XML-compliant:
+
+	<?php echo $title;?>
+
+	The ability to use the short start tag ('<?') can be turned on and
+	off using the short_tags() function. Whether it is enabled or not by
+	default is a compile-time option (normally set to enabled by default).
+
+
+[2]	Semicolons in if/elseif/else must be replaced with colons.
+
+	For example, the equivalent of:
+
+		if (expr);
+		  statements
+		  ...
+		elseif (expr);
+		  statements
+		  ...
+		else;
+		  statements
+		endif;
+
+	in PHP 3.0 would be:
+
+		if (expr):
+		  statements
+		  ...
+		elseif (expr):
+		  statements
+		  ...
+		else:
+		  statements
+		endif;
+
+	Note that the endif is followed by a semicolon and not a colon even in
+	PHP 3.0, which marks the end of the entire IF sentence.
+
+	Also note that the implementation of the colon-mode and curly-braces
+	mode in PHP 3.0 is identical, one isn't buggier than the other (note
+	that I'm not saying they're not buggy, though :)
+
+
+[3]	Semicolons in while loops must also be replaced with colons.
+
+	For example, the equivalent of:
+
+		while (expr);
+		  statements
+		  ...
+		endwhile;
+
+	in PHP 3.0 would be:
+
+		while (expr):
+		  statements
+		  ...
+		endwhile;
+
+	Note that the endwhile is followed by a semicolon and not a colon even
+	in PHP 3.0, which marks the end of the WHILE sentence.  As with the IF
+	statement, the implementation of the colon-mode and curly-braces mode
+	in PHP 3.0 is identical, one isn't buggier than the other.
+
+	Also note that failing to change the semicolon to a colon can result in
+	scripts that get stuck in the while loop because the loop-condition never
+	changes.
+
+
+[4]	$foo[0] is no longer identical to $foo.
+
+	In PHP/FI 2.0, a side-effect of the implementation caused $foo[0] to be
+	identical to $foo.  This is not the case in PHP 3.0.
+
+
+[5]	Expressions determine their types differently.
+
+	The way expressions are evaluated has changed radically in PHP 3.0.
+	Expressions are no longer given the type of the left argument, but are
+	assigned types taking both types into account, and regardless of which
+	is on the left side and which is on the right side.  On simple scripts
+	that should probably not effect you, but if you've relied on this fact
+	(even without realizing you do) it may change the way your scripts work.
+	Consider the next example:
+
+		$a[0]=5;
+		$a[1]=7;
+
+		$key = key($a);
+		while ("" != $key) {
+			echo "$key\n";
+			next($a);
+		}
+
+
+	In PHP/FI 2.0, this would display both of $a's indices.  In PHP 3.0, it
+	wouldn't display anything.  The reason is that in PHP/FI 2.0, because the
+	left argument's type was string, a string comparison was made, and indeed
+	"" does not equal "0", and the loop went through.  In PHP 3.0, when a
+	string is compared with an integer, an integer comparison is made (the
+	string is converted to an integer).  This results in comparing atoi("")
+	which is 0, and $key which is also 0, and since 0==0, the loop doesn't
+	go through even once.  The fix for this is simple, by replacing the
+	while statement with:
+
+		while ("" != stringval($key)) {
+
+	This would first convert the integer 0 to a string "0", and then
+	compare "" and "0", which are not equal, and the loop would go through
+	as expected.  As mentioned later, casting operators are supported in
+	PHP 3.0 for a quicker and more readable way of changing variables'
+	types. For example, you could use:
+
+		while ("" != (string)$key) {
+
+
+[6]	The structure of error messages has changed.
+
+	Although the error messages are usually more accurate, you won't be shown
+	the actual line of text and actual place in which the error occured.
+	You'll be supplied with the line number in which the error has occured,
+	though.
+
+
+[7]	The format string argument to echo is no longer supported.
+
+	Use printf(format,arg1,arg2,arg3,...) instead (unlimited arguments).
+
+
+[8]	The use of read-mode $array[] is no longer supported.
+
+	That is, you cannot traverse an array by having a loop that does $data =
+	$array[].  Use current() and next() instead.  Also, $array1[] = $array2
+	does not append the values of $array2 to $array1, but appends $array2
+	as the last entry of $array1 (see the multidimensional array support).
+
+
+[9]	Apache versions older than 1.2 are not supported anymore.
+
+	The apache module requires apache 1.2 or later (1.3-beta is supported).
+
+
+[10] Indirect references inside quoted strings
+
+	PHP2-style indirect reference inside quoted strings is no longer
+    supported.  That is, if $foo="bar", and $bar="abc", in PHP2,
+    "$$foo" would print out "abc".  In PHP3, this would print
+    "$bar" (the contents of $foo is replaced with "bar").
+    To use indirect reference in PHP3 inside quoted strings, you should use 
+    the new notation: "${$foo}".  The standard $$foo notation will work
+    outside of the quoted string.
+
+[11]
+		Some functions have changed names, are missing, or have been deprecated
+		by other functions
+
+	As a whole new rewrite, written by many more people and supporting many
+	more APIs than it's predecessor, there's a good chance some of the functions
+	you're used to from PHP/FI 2 aren't available in release 3, or have changed
+	names.  Many functions that do exist behave a bit differently, mainly
+	because they return different values for errors (false) but also for other
+	reasons.  We can't list all of these functions here, simply because drawing
+	a full comparison between the function sets of the two versions is way too
+	much work.  If a converted PHP/FI 2 script doesn't work for you, nothing
+	can replace the good old human eye going over the code, doublechecking
+	with the online manual that each function still does what you expected it
+	to do.
+
+[12]	Other incompatibilities.
+
+	It's not too unlikely that other documented behavior of PHP2 has changed
+	in this release.  If you think you've found an example, please mail
+	us at php-dev@php.iquest.net.  Even if you've found an undocumented
+	feature of PHP2 that stopped working in PHP3, we'd like to know about it
+	(although it's more than likely that it will not be supported).
+
+
+
+------------------------------------------------------------------------------
+
+
+New Language Features
+=====================
+
+[1]	Expressions
+
+	PHP 3.0 includes a rich implementation of expressions, much more advanced
+	than this of 2.0.  Just about any complex C-like or perl-like expression
+	would work.  Support was added for assignment operators (+=, -=, *= etc),
+	pre and post increment/decerement (e.g. $i++, ++$i) and the questionmark
+	operator ( (expr?expr:expr) ).  Every assignment is now an expression
+	with a value, which means stuff like $a = $b = $c = $d = 0;  would work.
+	It is difficult to describe the power of expressions within a few lines
+	of text, but if you're familiar with them, you probably get the picture.
+
+
+[2]	for loops are now supported.
+
+	for loops were fairly difficult to implement (in fact, we didn't find
+	any parallel interpreter that supports for loops anywhere (no, perl is
+	not an interpreter)).  The bottom line is that for loops work, and are
+	around 5% slower than comparable while loops (that may vary), but often
+	they're much nicer.
+
+	The syntax is identical to the one of C:
+
+		for (expr; expr; expr) statement;
+
+	or
+
+		for (expr; expr; expr) { statements ... }
+
+	The first expression is executed the first time the loop is encountered,
+	the loop is run as long as the second expression is evaluated as TRUE,
+	and after each iteration, the 3rd expression is evaluated.
+
+	Colon-mode FOR loops are also supported:
+	for (expr; expr; expr):
+		statements
+		...
+	endfor;
+
+
+[3]	do..while(expr) loops are now supported.
+
+	Like with its C parallel, the statements inside a do..while loop are
+	run once the first time the loop is encountered, and then as long as
+	the expression evaluates as true.
+
+	For example:
+
+		do {
+			statements;
+		} while ($i++ < $max);
+
+
+[4]	break and continue statements are now supported inside loops.
+
+	You can break out of loops, or continue to the next iteration of the
+	loop using these statements.  A special feature of PHP is the ability
+	to specify an expression argument to break or continue, which specifies
+	how many loops you want to break out from or continue to.  For example:
+
+		for ($i=0; $i<10; $i++) {
+			for ($j=0; $j<10; $j++) {
+				if ($j>5)
+					break;
+				if ($i>5)
+					break 2;
+			}
+		}
+	
+	The first break statement would end the inner loop every time $j is
+	greater than 5.  The second break statement would end both the inner
+	and outer loop when $i is greater than 5.
+
+	Note:  For this matter, switch statements are considered as loops.  So
+	if you write "break 2;" inside a switch statement, you would be asking
+	to break out of the switch, and the innermost loop in which is nested.
+
+
+[5]	Switched to C-style declaration of functions.
+
+	Here's a pretty useless function which makes a good example:
+
+		function concat($str1,$str2)
+		{
+			return $str1.$str2;
+		}
+
+	NOTE:	The old style function definition is still supported, to
+			allow easier upgrading from PHP/FI 2.0 scripts.  Simply
+			change 'function' to 'old_function' for these functions.
+
+
+[6]	OOP support
+
+	Classes and inheritance are supported to a limited extent in PHP 3.0.
+	Here's how to declare a simple class:
+
+		class simple_class {
+			var $property1,$property2;
+			var $property3=5;
+
+			function display() {
+				printf("p1=%d, p2=%d, p3=%d\n",
+					$this->property1,
+					$this->property2,
+					$this->property3);
+			}
+			function init($p1,$p2) {
+				$this->property1 = $p1;
+				$this->property2 = $p2;
+			}
+		};
+
+	Here's how to create an object of that class:
+
+		$obj = new simple_class;
+
+	At this point, $obj is an object with 2 uninitialized variables, 1
+	initialized variable, and 2 member functions.  No protection is made on
+	the internals of the object, and using its properties is simple:
+
+		$obj->property1 = 7;
+
+	would assign 7 to $property1 inside $obj.  Calling member functions is
+	also simple:
+
+		$obj->display()
+
+	would run the display() member function of $obj.  Note that the
+	implementation of display() uses the special variable $this, which is
+	replaced with the object the function is called on.
+
+	Inheritance is pretty simple too:
+
+		class complex_class extends simple_class {
+			var $property4="test";
+
+			function display() {
+				printf("p1=%d, p2=%d, p3=%d, p4=%d\n",
+					$this->property1,
+					$this->property2,
+					$this->property3,
+					$this->property4);
+			}
+		}	
+
+	Basically, the class complex_class inherits everything from its parent,
+	simple_class, except properties or member functions which override the
+	ones in the parent.  In this example, since we supply an alternative
+	display() function, it would be used with complex_class objects instead
+	of the display() function that was declared in simple_class.  On the other
+	hand, since we don't supply an alternative init() function, complex_class
+	objects would have the same init() function as simple_class objects do.
+
+	As with expressions, it's impossible to teach OOP in a few lines, and
+	personally I'm unclear as to how useful this would be in day to day
+	scripting.  If you like this, play with this until you figure it out :)
+
+	Objects can reside in arrays, and can contain arrays.  However,
+	a limitation of the current implementation doesn't allow an object
+	to contain an array of objects (actually, this is allowed, but
+	there's no way to address the properties of such an object directly,
+	but only indirectly).  For example, assuming $a[3] is an object,
+	$a[3]->b[2] is an object as well, you can't address the properties
+	of $a[3]->b[2] (i.e. you can't write $a[3]->b[2]->foo = "bar", for
+	instance).  
+
+
+[7]	Function pointers are now supported.
+
+	A simple illustrative example:
+
+		$func_ptr = "time";
+		$current_time = $func_ptr();
+
+	is identical to
+
+		$current_time = time();
+
+
+[8]	Indirect references are much more powerful.
+
+	For example, one can use the dollar operator an infinite amount of times:
+
+		$a = "b";
+		$b = "c";
+		$c = "d";
+		$d = "e";
+		$e = "Testing\n";
+
+		echo $$$$$a;
+
+	Would display $e's content, which is "Testing\n".
+
+	In addition, one can use complex expressions to generate variable names
+	using a perl-like notation:
+
+		$i="123";
+		${"test".$i} = 5;
+
+	would assign 5 to $test123.
+
+[9]	A string concatenation operator was added, '+' no longer concatenates strings.
+
+	A perl-like string concatenation operator was added, the '.' operator.
+	It converts both of its arguments to strings, and concatenates them.
+	For example:
+
+		$result = "abcd".5;
+
+	assigns "abcd5" to result.  Note that under PHP 3.0, the '+' operator
+	no longer performs concatenation if its arguments are strings.  Use
+	the '.' operator instead.
+
+[10]	Supports passing function arguments by references instead of by value.
+
+	Support for passing function arguments by reference instead of by value
+	has been added.  This doesn't result in having to change the function
+	implementations in any way, but, when calling the function, you can
+	decide on whether the variable you supply would actually be changed by
+	the function, or a copy of it.
+
+	Example:
+
+		function inc($arg)
+		{
+			$arg++;
+		}
+
+		$i=0;
+		inc($i);  # here $i in the outer scope wouldn't change, and remain 0
+		inc(&$i); # here $i is passed by reference, and would change to 1
+
+
+[11]	Support for multidimensional arrays.
+
+	(Or as Andi calls them, 'hyperdimensional variables'.)
+
+	The easiest way to define this support of PHP 3.0 is inductive -
+	arrays can contain any type of variables, including other arrays.
+	A simple example:
+
+		$a[0]=5;
+		$a[1]["testing"]=17;
+		$b["foo"]=$a;
+
+	Ok, so it may be not so simple.  Play with it, it's pretty powerful.
+
+
+[12]	Array initialization is now supported.
+
+	For example, let's say you want to initialize a lookup table to convert
+	number to month names:
+
+		$months = array("January", "February", "March",
+						"April", "May", "June", "July", "August",
+				 		"September", "October", "November", "December");
+
+	would assign $months[0] to be January, $months[1] to be February, etc.
+	Alternately, you may want the count to start at '1' instead of 0.
+	You can do so easily:
+
+		$months = array(1=>"January", "February", "March",
+						"April", "May", "June", "July", "August",
+						"September", "October", "November", "December");
+
+	Also, you can specify an index for every entry, not just the first one:
+
+		$first_names = array("Doe"=>"John", "Gates"=>"William",
+							"Clinton"=>"Bill" });
+
+	would assign $first_names["Doe"]="John", etc.
+
+
+[13]	Perl style lists now supported.
+
+	Multiple values from arrays may now be assigned into several
+	variables using one assignment.  For example:
+	
+		$str = "johndoe:x:555:555:Doe, John:/home/johndoe:/bin/tcsh";
+		
+		list($username,$passwd,$uid,$gid,$realname,$homedir,$shell) = 
+			explode(":",$str);
+	
+	Would assign 'johndoe' into $username, 'x' into $passwd, etc.
+
+
+[14]	Colons are supported in 'case' and 'default' statements.
+
+	For example:
+
+		switch($value) {
+			case 'A':
+				statement;
+				break;
+			case 'B':
+				statement;
+				break;
+			case 'C':
+				statement;
+				/* fall-through */
+			default:
+				statement;
+		}
+	
+	Semicolons are still supported, but when writing new scripts, they
+	should be phased out in favour of colons.
+
+
+------------------------------------------------------------------------------
+
+
+Non Language Related New Features
+=================================
+
+[1]	Persistent resource lists.
+
+	In plain english this means that there's now an easy way of writing the
+	SQL drivers so that they don't open and close the SQL link every time,
+	but instead open it the first time it's required, and then use it on
+	every later hit.  As of PHP 3.0a1, only the MySQL, mSQL and PostgresSQL
+	drivers have been changed (rewritten) to take advantage of this option.
+	To use it, use mysql_pconnect() instead of mysql_connect() (or the
+	equivalents for the two other databases).
+
+
+[2]	Configuration file.
+
+	PHP now has its own configuration file, and many compile-time options
+	of PHP2 are now configurable at runtime.
+
+
+[3]	Syntax Highlighting.
+
+	A syntax highlighter has been built into PHP 3.0, which means PHP 3.0 can
+	display your code, syntax highlighted, instead of executing it.
+	There are currently two ways to use the syntax highlighter.  One is to
+	use the show_source() statement.  This statement is identical to the
+	include() statement, except instead of executing the file, it displays
+	its source syntax highlighted.
+	The second way is possible only when running as an apache module, and is
+	to define a special extension for PHP 3.0 source files (e.g. .php3s)
+	and instruct apache to automatically syntax highlight them.
+
+
+[4]	Loadable modules.
+
+	This would have a huge impact on the Windows version, and would probably
+	be used in the UNIX environment as well.  One can now add PHP internal
+	functions in runtime by loading a dynamic module.  This is known to work
+	under Solaris, Linux and Win32 at this time, but would be ported to any
+	other capable platform if an incompatability is found.
+
+
+------------------------------------------------------------------------------
+
+
+Other Interesting Issues
+========================
+
+
+[1]	Improved performance.
+
+	The performance of PHP 3.0 is much better than the one of PHP/FI 2.0.
+	Memory consumption has been dramatically reduced in many cases, due
+	to the use of an internal memory manager, instead of apache's pools.
+	Speedwise, PHP 3.0 is somewhere between 2 and 3 times faster than
+	PHP/FI 2.0.
+
+
+[2]	More reliable parser.
+
+	After PHP 3.0 is well tested, it'll be pretty safe to say that it's
+	more reliable than PHP/FI 2.0 is.  While PHP/FI 2.0 performed well on
+	simple, and fairly complex scripts, a fundamental design difference
+	from PHP 3.0 makes it more prone to errors.  In PHP 3.0, obscure parser
+	problems are much less likely.
+
+
+[3]	Improved C API.
+
+	If you're a C coder, adding functionality to PHP was never easier.
+	A pretty well documented API is available (apidoc.txt), and you no longer
+	have to touch the parser or scanner code when adding your function.
+	Also, it's more complicated to 'go wrong' when implementing a PHP3
+	function than it was in PHP2 (no stack to maintain) - but of course,
+	you can mess up here too :)
+
+
+[4]	Name change.
+
+	PHP/FI 2.0 was renamed to PHP 3.0, and the meaning has changed from
+	'Personal Home Pages / Forms Interpreter' to 'PHP: Hypertext Preprocessor'.
+	'Personal' home pages was an understatement for PHP/FI 2.0, and is
+	definitely an understatement for PHP 3.0.

+PHP Coding Standards
+====================
+
+
+This file lists several standards that any programmer, adding or changing
+code in PHP, should follow.  Since this file was added at a very late
+stage of the development of PHP v3.0, the code base does not (yet) fully
+follow it, but it's going in that general direction.
+This is an initial version - it'll most probably grow as time passes.
+
+
+Code Implementation
+-------------------
+
+[1] Functions that are given pointers to resources should not free them
+
+For instance, function int mail(char *to, char *from) should NOT free
+to and/or from.
+Exceptions:
+
+  - The function's designated behavior is freeing that resource.  E.g. efree()
+  - The function is given a boolean argument, that controls whether or not
+    the function may free its arguments (if true - the function must free its
+    arguments, if false - it must not)
+  - Low-level parser routines, that are tightly integrated with the token
+    cache and the bison code for minimum memory copying overhead.
+    
+[2] Functions that are tightly integrated with other functions within the
+    same module, and rely on each other non-trivial behavior, should be
+    documented as such and declared 'static'.  They should be avoided if
+    possible.
+
+[3] Use definitions and macros whenever possible, so that constants have
+    meaningful names and can be easily manipulated.  The only exceptions
+    to this rule are 0 and 1, when used as false and true (respectively).
+    Any other use of a numeric constant to specify different behavior
+    or actions should be done through a #define.
+
+[4] When writing functions that deal with strings, be sure to remember
+    that PHP holds the length property of each string, and that it
+    shouldn't be calculated with strlen().  Write your functions in a such
+    a way so that they'll take advantage of the length property, both
+    for efficiency and in order for them to be binary-safe.
+    Functions that change strings and obtain their new lengths while
+    doing so, should return that new length, so it doesn't have to be
+    recalculated with strlen() (e.g. _php3_addslashes())
+
+[5] Use php3_error() to report any errors/warnings during code execution.
+    Use descriptive error messages, and try to avoid using identical
+    error strings for different stages of an error.  For example,
+    if in order to obtain a URL you have to parse the URL, connect,
+    and retreive the text, assuming something can go wrong at each
+    of these stages, don't report an error "Unable to get URL"
+    on all of them, but instead, write something like "Unable
+    to parse URL", "Unable to connect to URL server" and "Unable
+    to fetch URL text", respectively.
+
+[6] NEVER USE strncat().  If you're absolutely sure you know what you're doing,
+    check its man page again, and only then, consider using it, and even then,
+    try avoiding it.
+
+
+Naming Conventions
+------------------
+
+[1] Function names for user functions implementation should be prefixed with
+    "php3_", and followed by a word or an underscore-delimited list of words,
+    in lowercase letters, that describes the function.
+
+[2] Function names used by user functions implementations should be prefixed
+    with "_php3_", and followed by a word or an underscore-delimited list of
+    words, in lowercase letters, that describes the function.  If applicable,
+    they should be declared 'static'.
+    
+[3] Variable names must be meaningful.  One letter variable names must be
+    avoided, except for places where the variable has no real meaning or
+    a trivial meaning (e.g. for (i=0; i<100; i++) ...).
+
+[4] Variable names should be in lowercase;  Use underscores to seperate
+    between words.
+
+
+
+Syntax and indentation
+----------------------
+
+[1] Never use C++ style comments (i.e. // comment).  Always use C-style
+    comments instead.  PHP is written in C, and is aimed at compiling
+    under any ANSI-C compliant compiler.  Even though many compilers
+    accept C++-style comments in C code, you have to ensure that your
+    code would compile with other compilers as well.
+    The only exception to this rule is code that is Win32-specific,
+    because the Win32 port is MS-Visual C++ specific, and this compiler
+    is known to accept C++-style comments in C code.
+
+[2] Use K&R-style.  Of course, we can't and don't want to
+    force anybody to use a style she's not used to, but
+    at the very least, when you write code that goes into the core
+    of PHP or one of its standard modules, please maintain the K&R
+    style.  This applies to just about everything, starting with
+    indentation and comment styles and up to function decleration
+    syntax.
+    
+[3] Be generous with whitespace and braces.  Always prefer
+    if (foo) {
+		bar;
+	}
+	to
+	if(foo)bar;
+	
+    Keep one empty line between the variable decleration section and
+    the statements in a block, as well as between logical statement
+    groups in a block.  Maintain at least one empty line between
+    two functions, preferably two.
+
+Documentation and Folding Hooks
+-------------------------------
+
+In order to make sure that the online documentation stays in line with
+the code, each user-level function should have its user-level function
+prototype before it along with a brief one-line description of what the
+function does.  It would look like this:
+
+/* {{{ proto int abs(int number)
+   Return the absolute value of the number */
+void php3_abs(INTERNAL_FUNCTION_PARAMETERS) {
+   ...
+}
+/* }}} */
+
+The {{{ symbols are the default folding symbols for the folding mode in
+Emacs.  vim will soon have support for folding as well.  Folding is very
+useful when dealing with large files because you can scroll through the 
+file quickly and just unfold the function you wish to work on.  The }}}
+at the end of each function marks the end of the fold, and should be on
+a separate line.
+
+The "proto" keyword there is just a helper for the doc/genfuncsummary script
+which generates a full function summary.  Having this keyword in front of the
+function prototypes allows us to put folds elsewhere in the code without
+messing up the function summary.
+
+Optional arguments are written like this:
+
+/* {{{ proto object imap_header(int stream_id, int msg_no [, int from_length [, int subject_length [, string default_host]]])
+
+And yes, please keep everything on a single line, even if that line is massive.

+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+- Added an XML parsing extension using James Clark's "expat" library
+- Optimized parts of the token cache code.
+- Terminate on out-of-memory errors.  Until now, PHP could crash in out of
+  memory situations (clean-up, no real effect).
+- Unterminated comments in include files were being reported with the wrong line
+  number.  Fixed.
+- Added ImageCopy() and ImageColorDeallocate(). ImageCopy() is about
+  20% faster than ImageCopyResized(). ImageColorDeallocate() marks
+  palette entries free for reuse (by <mka@satama.com>).
+- In the CGI version, it was impossible to access resources (e.g. SQL links,
+  images) from user-defined shutdown functions.  Fixed.
+- Added optional third parameter to strpos() to specify the offset to
+  start searching from.
+- Fixed a crash bug in unset() when unsetting illegal variables (rare).
+- Made ImageInterlace and ImageTransparentColor parameters optional, and made
+  them return the current/new settings.
+- Optimized GetImageSize() <thies@digicol.de>.
+- Made odbc_autocommit() without args return status
+- Added connect workaround for OpenLink ODBC
+- Added minimal InterBase support. Tested only on 4.0 & Linux.
+- Fixed some memory leaks and bogus error messages in the URL handler of
+  the various file open functions.  Should only affect error handling
+  in bad URLs.
+
+October 5 1998 Version 3.0.5
+- mysql_field_flags now reports all MySQL flags and the result is suitable
+  for automatic parsing. Compatibility warning: The result format has
+  changed. If you have scripts parsing the result of this function, you
+  may need to adapt them.
+- Made nl2br() binary safe (not that it's of much use).
+- Fixed a bug in the API function getThis().  It affected mostly the dir
+  functions, if nested within objects.
+- Fixed a problem in require() in conjunction with switch(), and in some other
+  cases.  Also fixed an identical problem with the call_user_function() API
+  function.
+- Removed -lpthread when compiling with MySQL support.  It caused various
+  serious problems when compiled into Apache.
+- Add serialize() and unserialize() functions from jkl@njet.net

+- Added optional support for ASP-style <% %> and <%= tags
+- Fixed data loss problems with very large numeric array indices on 64-bit
+  platforms (e.g. DEC UNIX).
+- 2 cursor_type parameters for ifx_query() and ifx_prepare changed
+  to 1 (bitmask). Added a few constants for use in Informix module.
+- Added php3.ini option ifx.charasvarchar. If set, trailing blanks
+  are stripped from fixed-length char columns. (Makes life easier
+  for people using Informix SE.)
+- Static SNMP module which compiles with ucd-snmp 3.5.2
+- fixed imap_header & header_info from crashing when a header line
+  is > 1024 characters.
+- Added patch for rfc822_parse_adr to return an array of objects instead 
+  of a single object. 
+- Informix Online 7.x & SE 7.x support now fairly complete and stable
+- Add dbase_get_record_with_names() function
+- Added a special case for open_basedir. When open_basedir is set to "."
+  the directory in which the script is stored will be used as basedir.
+- Include alloca.c in the distribution for platforms without alloca().
+- Improved stripping of URL passwords from error messages - the length of the
+  username/password isn't obvious now, and all protocols are handled properly
+  (most importantly, http).
+- Copying objects that had member functions with static variables produced
+  undetermined results.  Fixed.
+- Added function lstat() and cleaned up the status functions,
+  added tests for file status functions (this may break on some plattforms)
+- Fixed is_link() - it was returning always false.
+- Fixed apache_note() - it was corrupting memory.
+- New Function.  void get_meta_tags(string filename);  Parses filename until
+  closing head tag and turns all meta tags into variables prefixed with 'meta_'.
+  The below meta tag would produce $meta_test="some string here"
+	<meta name="test" content="some string here">
+- Generalized some internal functions in order to better support calling
+  user-level functions from C code.  Fixes a few sporadic problems related
+  to constructors inside eval() and more.
+- Fixed an endless loop in explode(), strstr() and strpos() in case of an
+  invalid empty delimiter.
+- rand() now accepts two optional arguments, which denote the requested range
+  of the generated number.  E.g., rand(3,7) would generate a random number
+  between 3 and 7.
+- Added M_PI constant.
+- Added deg2rad() and rad2deg() for converting radians<->degrees.
+- ImageArc() misbehaved when given negative angles, fixed.
+- Fixed a bug in ereg() that may have caused buglets under some circumstances.
+- Added imap_status
+- Shutdown functions, registered via register_shutdown_function(), could never
+  generate output in the Apache module version.  Fixed.
+- Brought IMAP docs into sync with acutal imap code
+- imap_fetchstructure now takes in optional flags 
+- Fix potential core dumps in imap_append and imap_fetchtext_full

+- Fix shutdown warning in the LDAP module
+- *COMPATIBILITY WARNING* imap_fetchstructure() "parametres" object and property
+  name changed to "parameters" to match the documentation and to be consistent
+  with the rest of the API.
+- Delete uploaded temporary files automatically at the end of a request
+- Add upload_max_filesize and correponsing php3_upload_max_filesize directive
+  to control the maximum size of an uploaded file.  Setting this to 0 would
+  completely eliminate file uploads.
+- Force $PHP_SELF to PATH_INFO value when running in CGI FORCE_CGI_REDIRECT mode
+- Add apache_lookup_uri() function which does an internal sub-request lookup
+  and returns an object containing the request_rec fields for the URI.  (Yes,
+  you have to be a bit of a gearhead to figure this one out)
+- Fix a few signed char problems causing functions like ucfirst() not to work
+  correctly with non-English charsets
+- md5() function not binary safe - fixed
+
+August 15 1998 Version 3.0.3
+- Changed the name of fopen_basedir to open_basedir, to be a little more
+  accurate about what it does.
+- Added Hyperwave module
+- Added config-option (php3_)enable_dl <on/off>. This enables/disables the
+  dl() function.  In safe-mode dl() is always disabled.
+- Auto-prepended files were crashing under some circumstances - fixed.
+- Win32 mail fixes provided by walton@nordicdms.com
+- Comparing between arrays and/or objects now generates a warning (it always
+  returns false, as it used to;  no comparison is made)

+  appear twice under certain circumstances.
+- Fix bug in filetype() function related to symlinks
+- Started integrating Informix SE support to PHP configure/makefile setup.
+- gdttf roundoff fixes from ellson@lucent.com
+- Added initial Informix SE support files from Danny Heijl - This code still
+  needs to be integrated into the PHP configure/makefile setup and the code
+  itself needs more work.
+- return in the global scope now terminates the execution of the current file.
+- Added the ability to register shutdown function(s), via
+  register_shutdown_function($function_name).
+- Clean up const warnings
+- Add write support to ftp fopen wrappers
+- Add strspn() and strcspn() functions
+- On systems without strerror use Apache version if compiling as Apache module
+- The PHP start tag was being ignored under some circumstances - fixed.
+- The db, dbase and filepro functions are now Safe-Mode aware.
+- Added config-option (php3_)fopen_basedir <path>. This limits the directory-
+  tree scripts can open files in to <path>.
+- Fixed pg_loreadall that didn't always return all the contents in a PostgreSQL
+  large object. Also, doesn't pass through anything if method is HEAD.
+- configure fix to create target Apache module dir
+- Fix core dump in imageTTFtext() function
+- Added static IMAP support
+- Syntax highlighting was generating additional whitespace - fixed.
+- Added ucwords.  Works like ucfirst, but works on all words within a string.
+- Added array_walk() - apply user function to every element of an array
+- Added usort() - array sort that accepts a user defined comparison function!
+- Added the ability to call user-level functions and object methods on demand
+  from the C source using a completely generalized, slick API function.
+  Miracles do happen every once in a while.
+- Added constructors.  Don't even squeek about destructors! :) (we mean that)
+- Make pg_lowrite() binary safe
+- Fixed mod_charset option in ./setup
+- Fixed rewinddir() and dir()::rewind() under Win32 (they didn't work before).
+- Add Win32 COM support!  By-name referencing is supported using the IDispatch
+  interface (automation).  Available functions - COM_Load(), COM_Invoke(),
+  COM_PropGet() and COM_PropSet().
+  
+July 20 1998 Version 3.0.2a

+  to make it possible to configure the look of error messages displayed by PHP
+  to some extent
+- Added E_ERROR, E_WARNING, E_NOTICE, E_PARSE and E_ALL constants, that can be
+  used in conjunction with error_reporting()
+  (e.g. error_reporting(E_ERROR|E_WARNING|E_NOTICE);
+- Fixed a crash problem with classes that contained function(s) with default
+  values.
+- Fixed a problem in the browscap module.  Browscap files weren't being read
+  properly.

+- New PostgreSQL functions:  pg_fetch_row(), pg_fetch_array()
+  and pg_fetch_object()
+- Fix a segmentation fault when calling invalid functions in certain
+  circumstances
+- Fix bug that caused link-related functions to not pay attention to

+- Several fixes to the configuration file parser
+- LDAP fixes - fixed return values on several functions
+
+May 23 1998 Version 3.0RC5
+- The BC math library functions now compile in by default.
+- Fixed a bug in virtual() and other types of SSI's (e.g. <!--#exec).  Under
+  certain circumstances, this used to result in random problems.
+- Fixed a bug in virtual().  It was misbehaving if it was called before any
+  other output.
+- Added mysql.default_port, mysql.default_host, mysql.default_user and
+  mysql.default_password ini-file directives.
+- Improved handling of the MySQL default port.  It now honors /etc/services
+  and $MYSQL_TCP_PORT.
+- Fixed a crash in opening of broken ftp:// URLs, and improved error reporting
+  in opening of URLs.
+- Fixed several non-critical scanner issues with syntax highlighting mode and
+  the <script language=php> tag.
+- Fixed fseek on windows.  (windows only): fseek will not return proper results
+  on files opened as text mode.  PHP uses binary mode as the default for file
+  operations, but this can be overiden by fopen.  Do not open files in text
+  mode and use fseek on them!
+- Add strpos() function
+- Added zlib module, requires zlib >= 1.0.9
+- Improved the module API implementation.  Dynamic modules may now register
+  persistent resources (not that it makes much sense, but at least PHP
+  won't crash).  The API itself remains unchanged.
+- bcmod() wasn't always behaving like modulus should behave (it was behaving
+  exactly like GNU bc's % operator).  Fixed.
+- Changed the Sybase-DB module to always return strings, instead of auto-typing
+  result sets.  This was done for consistency with the other database modules,
+  and in order to avoid overflows due to the platform-dependant limitations
+  of the numeric data types of PHP.  You can turn compatability mode on using
+  the sybase.compatability_mode directive in the php3.ini file.
+- Fixed problems with the TINYINT field in the Sybase-CT module.
+- Applied some small speed optimizations to the Sybase-DB module querying code.
+- Added 'numeric' and 'type' properties to the object returned by
+  sybase_fetch_field().
+- The 'new' operator doesn't accept all expressions anymore.  Instead, it
+  accepts a class name, or a variable reference (scalar, array element, etc).
+- Add ora_numcols() function
+- Add ora_do() and ora_fetch_into() functions to Oracle driver
+- Add persistent connection support to Oracle driver
+- Make Oracle driver clean up open connections and open cursors automatically
+- Added fread() and fwrite() that properly handle binary data.
+- Add Ora_ColumnSize() to Oracle code
+- The string "0" means FALSE again.  This was done in order to maintain type
+  conversion consistency.
+- Added solid_fetch_prev() for fetching the previous result row from Solid.
+- Huge integers are now automatically converted to floating point numbers
+  (that have a wider range).
+- Floating point numbers are now displayed using scientific notation when
+  they're extremely big or extremely small.  The 'precision' php3.ini directive
+  no longer designates the number of decimal digits, but rather, the maximum
+  number of significant digits required.
+- Added support for scientific notation for floating point numbers (e.g. 1E7)
+  throughout the entire language.
+- Fixed a potential/probable memory corruption problem with HEAD request
+  handling.
+- Using un-encapsulated strings now generates a NOTICE-level warning
+  (e.g. $a = foo; instead of $a = "foo";)
+- Added defined("name") function to check if a certain constant is defined
+  or not.
+- Support new Apache mechanism for setting SERVER_SUBVERSION
+- Added PHP_OS and PHP_VERSION constants
+- Added the ability to define constants in runtime!  Constants are script-wide,
+  (there's no scope, once the constant is defined, it's valid everywhere).
+  Syntax is define("name", $value [, $case_insensitive]).  'name' can be any name
+  that is a valid variable name, *without* the $ prefix.  'value' can be
+  any *scalar* value.  If the optional 'case_insensitive' parameter is 1,
+  then the constant is created case-insensitive (the default is case
+  sensitive).  Note:  define() is currently *NOT* supported in preprocessed
+  scripts.
+- Added general support for constants.  The Syslog constants (e.g.
+  LOG_ERR, LOG_CRIT, etc.) should be accessed as constants from now on (that
+  is, without a $ prefix).  You can still set define_syslog_variables to On
+  in the php3.ini file if you want to define the various $ variables.  The
+  default for this directive in the php3.ini-dist file has been changed to
+  Off.
+- The configuration file path variable now expands . and .. into their
+  respective directories.  You can obtain the path of the php3.ini file
+  that was used by printing get_cfg_var("cfg_file_path").
+- Fixed a crash-recovery parser crash ($a=7; $a[3]+=5;)
+- Add gmmktime() function
+- Fixed a crash with implode() and empty arrays.
+- Fixed a bug that, under fairly rare circumstances, caused PHP not to
+  recognize if(), require() and other statements as statements, and
+  to complain about them as being unsupported functions.
+- Beautified php3.ini-dist and added more comments to it.  Also changed
+  the behavior of the configuration file parser to be brighter about
+  the various constants (TRUE/FALSE/ON/OFF etc).
+- Fixed a bug in openlog() - the specified device name was being mangled.
+- Memory leaks were sometimes reported erroneously - fixed.
+- Improved the convertor to handle some quirks of the PHP/FI 2 parser with
+  comments.
+- Fixed number_format() to properly handle negative numbers, and optimized it
+  a bit.
+- Fixed static variables inside class member functions.  Note that using such
+  static variables inside member functions usually defeats the purpose of
+  objects, so it is not recommended.
+- Fixed a bug in fpassthru() (the file was being closed twice).
+- Added strftime().
+- Add set_socket_blocking() function to control blocking on socket fd's
+- The sendmail_path in php3.ini was being ignored - fixed.
+- Fixed a bug with file upload, with files that contained the MIME boundary
+  inside them.
+- Fixed a bug with form variables of type array, with spaces in their
+  index (e.g. name="foo[bar bar]").
+- gd-1.3 autodetect and support
+- Year 2000 compliance is now togglable from the php3.ini file.  Setting PHP
+  to be y2k compliant effects the way it creates cookies, and means it'll
+  NOT work with many browsers out there that are not y2k compliant!  For
+  that reason, the default for this option is off.
+- safe mode / fix from monti@vesatec.com
+- Integrated the FreeType support in the GD extension.
+- Added --with-gd=DIR and --without-gd options to configure
+
+April 18 1998 Version 3.0 Release Candidate 4
+- Auto-prepended and auto-appended files were reporting the wrong filename
+  in errors and in __FILE__ - fixed.
+- Fix GPC problem related to mixed scalar and array vars with the same name
+- Made putenv() Apache-safe.  Environment variables may no longer leak in
+  between requests.
+- The trailing semicolon is no longer required in class declarations.
+- Fixed a memory leak in the (array) and (object) operators under certain
+  conditions.
+- <script> tags weren't working unless short tags were enabled - Fixed.
+- Fixed a bug in certain array indices that weren't treated as numbers
+  even though they looked like numbers (e.g. "10", "20").
+- Changes to support renamed API functions in Apache-1.3
+- Fixed the -p and -e command line switches
+- Fix a segfault when calling command line version without parameters
+- Fix for feof() when used on a socket

+- Fix Apache build problems introduced in RC2
+- $a["0"]==$a[0] fix
+- Apache-1.3 build changes to support 100% automatic builds and shared library
+  module builds.  See INSTALL file.
+ 
+March 30 1998 Version 3.0 Release Candidate 2
+- Changed the socket implementation under UNIX to not use FILE pointers, in
+  order to work around the buggy Solaris libc (and possibly buggy libc's
+  in other platforms).
+- Fixed a bug in min() and max() with certain arrays.
+- *WARNING* Move Apache 1.3 php3 file install to src/modules/php3 instead of 
+  src/modules/extra.  Make sure you change your AddModule line correctly
+  in your Apache Configuration file.  This change is to take advantage of 
+  new Apache-1.3 configuration mechanism which makes it easier to build an
+  Apache server with PHP automatically enabled.  It will also help building
+  a shared library module version of PHP soon.
+- Fixed a crash bug with auto-appended files.
+- Made --enable-discard-path work on all Unix servers #!/path/php CGI scripts 
+  should now work everywhere.  I have tested on Apache, WN and Netscape 2.0
+- Made $a["123"] and $a[123] be identical.  $a["0123"] is still different,
+  though.
+- Added 'precision' ini directive, to set the number of decimal digits
+  displayed for floating point numbers (default - 6).
+- Made integer/integer divisions evaluate to floating point numbers when
+  applicable (e.g., 5/2==2.5(float), but 4/2==2(int))
+- Get rid of reliance on tied streams and move all socket reads and writes
+  to recv/send calls
+- Cleaned up head.c a bit and fixed CGI SetCookie order problem
+- Changed default variable parsing order to Get-Cookie-Post (GPC)
+- Fixed setup so it has all configure options and defaults.
+- Added optional decimal point and thousands seperator to number_format()
+  e.g., number_format(1500,2,',','.') == 1.500,00
+- Fixed cgi bug in windows that prevented files from being parsed on many
+  systems and servers.
+
+March 23 1998 Version 3.0 Release Candidate
+- Added support for the Raima database (ALPHA)
+- Fixed a bug in persistent PostgreSQL links and the connection-string method.
+- Added EXTENSION_STATUS file, that specifies the stability and status of
+  every module in the distribution.
+- Added optional parameters to user functions with default values, variables
+  that are forced to be passed by reference and variables that can be
+  optionally passed by reference.  The ini file directive
+  'ignore_missing_userfunc_args' is no longer supported.
+- Added fhttpd support (by Alex Belits)
+- Improved performance by approximately 20-30%.
+- Added mysql_error(), mysql_errno() (if available) and msql_error().
+  Errors coming back from the database backend no longer issue warnings.
+  Instead, use these functions to retreive the error.
+- Patched count(), each(), prev(), next(), reset() and end() to work around
+  the implementation side effects of unset().  As far as the users are
+  concerned, this should be transparent now (even though it's slower now,
+  until it's thoroughly fixed in 3.1).
+- Added number_format().  number_format(2499,2)=='2,499.00'.
+- error_reporting() now sets the error reporting level to the supplied
+  argument, without any interpretations.
+- Fixed a lookahead parser bug that occured under rare circumstances.
+- Change the comparison operators to compare numeric strings as numbers.  If
+  you want to compare them as strings, you can use the new C-like strcmp()
+- Fixed Ora_GetColumn() bug when fetching strings
+- Added Ora_ColumnName() and Ora_ColumnType()
+- Preliminary LONG and LONG RAW support in Oracle extension
+- Add \123 and \xAB style octal and hex escapes to "" and `` strings
+- Add "-c" command line flag for specifying path to php3.ini file
+- Improved list() so that elements can be skipped, for example:
+  list($name,,,$realname) = explode(":",fgets($passwd_file));
+- Fixed a tiny bug in the hash initialization which caused excessive use of
+  memory. Report and fix by short@k332.feld.cvut.cz
+- Fixed strtolower() and strtoupper() to work with 8-bit chars
+- Fixed to compile and run on SunOS 4.1

+  and didn't work with arrays.
+- Made [m,My]SQL create/drop database functions return success status
+- Fixed some memory leak/crash problems in the Adabas module
+- Added each() in order to allow for easy and correct array traversing.
+- Make Apache module version respect LOCALE setting
+- Add support for Apache 1.3b6+ ap_config.h file
+- Fixed a nasty corruption bug in eval() and show_source() that resulted in
+  script termination (e.g. eval("exit();").
+- Fixed a syntax highlighting problem with keywords used as variable
+  names.
+- Fixed a possible crash and/or file descriptor leak
+- Fixed line number being off by one in #! shell style execution

+  which are refered to as objects.
+- Fixed several fields that were being incorrectly read in Sybase CT.
+- Fix Apache-1.3 related SIGHUP problem which was preventing php3.ini from 
+  getting re-read on a SIGHUP
+- *** WARNING *** Downwards incompatible change:  The plus operator (+) is not
+  longer overloaded as concatenation for strings.  Instead, it converts its
+  arguments to numbers and performs numeric addition.
+- Add Stig and Tin's bdf2gdfont script to extra/gd directory
+- Added join() as an alias to implode()
+- Made implode() accept arguments in the order used by explode() as well

+- Fixed a 'memory leak' with strtok()
+- echo/print now handle binary data correctly.
+- NEW now accepts any expression for the class name argument.
+- Add ImageDashedLine() GD function
+- Add arg_separator .ini directive so the '&' GET method separator can be

+  directive works as well.
+- Walked around an implementation side effect of switch().  <? switch(expr) { ?>
+  now works.
+- Added memory caching, resulting in a significant performance boost
+- Added support for for(): .. endfor; loops
+- Added a new predicate - empty($var).  Returns true if $var is not set,
+  or is FALSE.  Returns false otherwise.
+- Added is_integer() (same as is_long()) and is_real() (same as is_double()).
+- Added sizeof() as an alias to the count() function
+- Added --enable-force-cgi-redirect, to prevent the CGI from working if
+  someone directly accesses PHP not through Apache's CGI redirect
+  (off by default).
+- Fixed marking of deleted dBase records. Noticed by Simon Gornall
+  <simon@oyster.co.uk>.
+- Fixed fixed "%%" bug in [s]printf
+- Fixed a UMR (initialized memory read) in the Oracle code

+  dies).
+- Fixed a crash bug with StrongHold and secure pages
+- Fixed StrongHold installation
+- Optimized the function call sequence a bit.
+- Fixed Sybase/CT date/datetime/money fields work to correctly.
+- Fixed Apache module startup problems - php3_module_startup should only be
+  called once.
+- Fixed ord() with characters >127
+- Fixed bug in file_exists() function
+- Fixed stripslashes() to remove the escaping quote (instead of backslash)
+  in case magic_quotes_sybase is true.
+- Also make echo and print automatically remove trailing decimal zeros.
+- Added htmlentities(), currently handling only ISO-8859-1 entities
+- "0" is no longer considered false, the only string which is false is the
+  empty string "".

+- Fixed a file descriptor leak in the configuration parser.
+- Fixed a few buglets with syntax highlighting with certain language keywords
+- Added functions to control minimum severity level of Sybase messages to
+  display.
+- Added highlight_string() - behaves like highlight_file(), only instead
+  of highlighting a file, it syntax highlights the contents of its
+  argument.
+- Renamed show_source() to highlight_file().  show_source() is still
+  supported for downwards compatability.
+- Fixed a bug in class inheritence - member functions with upper case
+  letters in their names couldn't be redefined.
+- Made chown(), chgrp() and chmod() return TRUE/FALSE instead of 0/-1.
+

+- Fixed file copy on Win32
+- MIME file uploads fixed on Win32
+- Added contributed icons by Colin Viebrock (undex extra/icons)

+- Fixed bug that allowed the file() and readfile() to open files in the
+  include path inadvertantly.
+- Fixed a (documented) bug in printf()/sprintf() with hard limited strings

+- Optimized several quoted string routines.
+- Added error_log ini directive to select where errors get logged when
+  log_errors is turned on or the error_log() function is used.

+  to the script output.  Use the new display_errors and log_errors
+  php3.ini directives.

+- Fixed a bug in the elseif() construct.  The expression was being evaluated
+  even if a previous if/elseif already evaluated to true and got executed.

+  prevented this feature from working on certain platforms.
+- PHP would now warn you with E_NOTICE about unknown escape characters,
+  e.g. "\f".  It would still be considered as a backslash followed by f,
+  but the proper way of writing this is "\\f" or '\f'.
+- Added support for ${...} inside encapsulated strings.  Supported:  ${foo},
+  ${foo[bar]}, ${foo[0]}, ${$foo[$bar]}, ${$foo->bar} and ${$foo}
+- Fixed a bug in automatic persistent link reconnect of the Sybase/DB module.
+  Thanks to Steve Willer for finding that 'stealth' bug!

+- Make dbase_get_record include a 'deleted' field that indicates whether
+  that record had been marked for deletion.
+- Fixed bug in dbase library that stomped on the deleted flag of the first
+  record in the file if it was set. (Thanks to colins@infofind.com.)
+- Fixed putenv() to not report a memory leak and possibly prevent a bug

+- Fixed MySQL Info function on Win32 platform
+- Fixed compilation of syntax highlighting mode
+
+January 17 1998 Version 3.0b3
+- Added mysql support under windows ;)  happy happy joy joy
+- Fixed dbase.dll for Win32 to actualy load now.
+- Enhanced the convertor to recognize ?> as a php-close-block as well.
+- Fixed potential SetCookie() core dumps
+- Changed print to be an expression instead of a statement.  That means you can
+  now do stuff like foobar() or print("Unable to foobar!").  echo has NOT been
+  changed.
+- Removed the flex optimization flags to reduce the size of the scanner
+- Added memory leak logging into apache log files (apache module only)
+- Fixed a nasty bug in one of the internal stacks.  This may have caused
+  random crashes in several occassions.

+- Added get_cfg_var() to enable checking cfg file directives from within
+  a script.
+- Fixed a bug with urlencode() and characters 0x80-0xff

+  backslashes other than valid existing back references in the second
+  argument are no more evaluated as escape sequences.
+- Fixed a bug in the configuration file loader and safe mode.
+- Fixed a bug with configuration variables taken from the environment.
+- Added <script language=php> </script> as PHP open/close tags, to allow
+  the use of editors such as Microsoft Frontpage.

+  /usr/local/lib properly.
+- Added support for \r\n line endings
+- Fixed a bug that may have prevented POST method variables from working 
+  with certain scripts when using the CGI version.
+- Convertor:  Added support for single-quoted strings

+  rows (update, insert, etc).
+
+December 22 1997 Version 3.0b2
+- Changed variable type conversions that do not specify base to always use
+  base 10.  "010" is no more 8, it is 10.  Use intval ($x, 0) to get C-style
+  octal and hex numbers recognized.
+- Fixed a possible segfault bug in several functions, when using the concat
+  operator and possibly other operators/functions.

+- fixed mail() on windows, also fixed memory leaks in mail on windows
+- added sendmail_from to handle return route on windows
+- Changed the way the config file is searched.  The file name is now
+  php3.ini (hardcoded), and it'll be looked for in:  local directory, $PHPRC
+  and builtin path designated by ./configure under UNIX or Windows directory 
+  under Windows.
+- Fixed ereg_replace replacing empty matches and a one off buffer overflow
+- Fixed File upload on windows platform
+- Fixed a bug that caused 'HTTP/1.1 100 Continue' messages with 
+  Internet Explorer 4.0 and certain scripts that receive POST variables
+- Get/POST/Cookie data variables are from now *ALWAYS* strings.  If you want
+  to use them in integer/real context, you must explicitly change their types.
+  This was done in order to avoid possible loss of data when doing these
+  conversions automatically.
+- Variables named as keywords are now allowed (e.g. $function, $class, etc)
+- Fixed a problem with msql() and mysql() with NULL fields
+- Fixed a segfault bug with class declarations
+- Fixed bugs with FOR loops and include() from within eval()
+- Changed include() to be executed conditionally.  PHP-3.0 efficient
+  unconditional include is now require()
+
+December 08 1997 Version 3.0b1
+- Switched to public beta test phase
+- Generalized unset() and isset() to work on any type of variables, including
+  specific array indices or object properties (e.g., unset($a[4]) now works).
+- Added support for object references inside encapsulated strings
+  (for example, 'echo "Username:  $user->name"' now works)
+- Added arbitary precision math support (basic operations with
+  unlimited range numbers, and support for unlimited decimal digits)
+- Apache module can now handle preprocessed scripts (by using:
+	AddType application/x-httpd-php3-preprocessed .php3p
+  in the Apache configuration)
+- Made settype() pass its first parameter by value.  Improved it to be able
+  to convert to arrays and objects (originally by Steve Willer)
+- Implemented CPU time limit on scripts when setitimer() is available
+- Computed field names in the Sybase/CT and Sybase/DB modules are now named
+  computed, computed1, computed2, ...
+- Added Sybase/CT client/server message handlers and updated the Sybase/DB ones
+- Made the regexp function automatically take arguments by reference
+  when necessary
+- Added builtin support for auto append and prepend in the parser level
+- Improved the Sybase/CT sybase_query().  Should be more stable now, and
+  hopefully work with a wider range of queries.  It's difficult to work
+  without docs, though, so it may still not be 100% right...
+- Changed error messages to show error type, file and line with bold
+- Added support for autoprepend and autoprepend
+- Added some more warning flags if gcc is used
+
+December 03 1997 Version 3.0a4
+- Improved the internal functions API - no need to explicitly pass
+  parameters by reference to internal functions that specifically
+  require them, e.g. sort(), ksort(), reset(), count(), etc.
+  This is *STILL* downwards compatible with the previous alphas,
+  in the sense that you can explicitly pass the arguments by reference
+  if you want to.
+- use srandom/random instead of srand/rand if available
+- Added [m,My]sql_listfields() for downwards compatability
+- -p now replaces .php3 extension with .php3p (otherwise it adds .php3p)
+- Added C++ style comments (// comment)

+- Added \0 back reference for full string match to *reg*_replace and
+  added backslash escaping to replace string
+- Fixed a few bugs in the Sybase DB-library module.
+- Added Sybase CT-library support.  It should be considered experimental.
+  Syntax is identical to the one of the DB-library.  Allows people to
+  connect to MS-SQL servers from Linux without having to pay for a
+  library!
+- Beautified phpinfo()
+- Add ImageColorClosest() and ImageColorExact() GD functions
+- Make all .ini directives work as Apache .conf directives as well
+- Added PHP2-like File() function with PHP3 URL support
+- Upgraded the Sybase interface.  It's practically MySQL compatible now!
+  Among other things, added sybase_fetch_array() and sybase_fetch_object().
+- Fixed problem in multi dimensional array handling and self modifying
+  operators (+=, -=, etc).
+- Safe Mode file open implementation
+- SVR3 portability problem fix
+
+November 23 1997 Version 3.0a3
+- Made the global statement behave like PHP 2 with undefined variables
+- Added msql_fetch_object() and msql_fetch_array()
+- Switched between the 1st and 2nd parameters to explode(), so that it acts
+  like split()
+- Fixed passthru(), exec() and system() functions

+  (The default is to assume you want to do a base 10 conversion.)
+- Implemented SQL safe mode for MySQL
+- Read UploadTmpDir from php3.ini instead of apache conf files
+- Added mysql_fetch_object() and mysql_fetch_array()

+The core of PHP 3.0 is considered to be stable at this time.  However, some of
+the modules that are bundled with it are still undergoing development, or
+contain known bugs.  The purpose of this file is to document the status of
+each module (extension).  Patches to unstable modules will be available through
+the CVS, and through periodic maintenance releases.
+
+Stability scale:
+Rock solid - We believe it's safe to base a production site on it.
+Stable     - It should be safe to base a production site on it.
+             Isn't rated as rock-solid because it contained problems
+             in the not-so-far past, or doesn't have enough users
+             to test it to know it's rock solid.
+Beta       - This module probably contains bugs, sometimes even known
+             bugs.  You can give it a try and there's a good chance
+             it'll work fine, but it might not be a good idea to base
+             a production site on it.
+Alpha      - This module is in initial development steps.  Don't trust
+             it, play with it at your own risk.
+Deprecated - This module is only available for downwards compatability,
+             and will not be supported in any way.  The code quality
+             is usually around the Beta status.
+             
+The standard disclaimers apply, that is, if a rock-solid module blows up on
+you and ruins your site, nobody in the PHP development team is responsible.
+We'll probably try to help, though.

+Installation Instructions for PHP3
+----------------------------------
+
+For the impatient here is a quick set of steps that will build PHP3
+as an Apache module for Apache 1.3.0 with MySQL support.  A more verbose 
+explanation follows.
+
+
+QUICK INSTALL
+
+gunzip apache_1.3.x.tar.gz
+tar xvf apache_1.3.x.tar
+gunzip php-3.0.x.tar.gz
+tar xvf php-3.0.x.tar
+cd apache_1.3.x
+./configure --prefix=/www
+cd ../php-3.0.x
+./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars
+make
+make install
+cd ../apache_1.3.x
+./configure --prefix=/www --activate-module=src/modules/php3/libphp3.a
+ (The above line is correct!  Yes, we know libphp3.a does not exist at this
+  stage.  It isn't supposed to.  It will be created.)
+make
+ (you should now have an httpd binary which you can copy to your Apache bin dir)
+cd ../php-3.0.x
+cp php3.ini-dist /usr/local/lib/php3.ini
+You can edit /usr/local/lib/php3.ini file to set PHP options.
+Edit your httpd.conf or srm.conf file and add:
+  AddType application/x-httpd-php3 .php3
+
+
+VERBOSE INSTALL
+
+Installing PHP3 can be done in four simple steps:
+
+1. Unpack your distribution file.  
+
+   You will have downloaded a file named something like php3xn.tar.gz.
+   Unzip this file with a command like: gunzip php3xn.tar.gz
+
+   Next you have to untar it with: tar -xvf php3xn.tar
+
+   This will create a php-3.0.x directory.  cd into this new directory.
+
+2. Configure PHP3.
+
+   You now have to choose the options you would like.  There are quite
+   a few of them.  To see a list, type: ./configure --help
+
+   You can also use the supplied 'setup' script, which will ask you
+   a series of questions and automatically run the configure script
+   for you.
+
+   The only options that you are likely to want to use are the ones in
+   the last section entitled, "--enable and --with options recognized:"
+
+   A popular choice is to build the Apache module version.  You need
+   to know where the source code directory for your Apache server is
+   located.  Then use an option like: --with-apache=/usr/local/src/apache
+   if that is your Apache source code directory.  If you only specify
+   --with-apache, then it will default to look for your Apache source 
+   in /usr/local/etc/httpd.
+
+   NOTE: The directory you specify should be the top-level of the
+   unpacked Apache (or Stronghold) distribution. The configure program
+   will automatically look for httpd.h in different directories under that
+   location depending on which version of Apache, including Stronghold,
+   you are running.
+
+   For MySQL support, since newer versions of MySQL installs its various
+   components under /usr/local, this is the default.  If you have
+   changed the location you can specify it with: --with-mysql=/opt/local
+   for example.  Otherwise just use: --with-mysql
+
+   *NOTE*  If you are using Apache 1.3b6 or later, you should run the 
+   Apache Configure script at least once before compiling PHP.  It 
+   doesn't matter how you have Apache configured at this point.
+
+3. Compile and install the files.  Simply type: make install
+
+   For the Apache module version this will copy the appropriate files
+   to the src/modules/php3 directory in your Apache distribution if
+   you are using Apache 1.3.x.  If you are still running Apache 1.2.x
+   these files will be copied directly to the main src directory.
+
+   For Apache 1.3b6 and later, you can use the new APACI configuration
+   mechanism.  To automatically build Apache with PHP support, use:
+
+       cd apache_1.3.x
+       ./configure --prefix=/<path>/apache \
+                   --activate-module=src/modules/php3/libphp3.a
+       make
+       make install
+
+   If you do not wish to use this new configuration tool, the old
+   install procedure (src/Configure) will work fine.
+
+   If you are using the old Apache ./Configure script, you will have to 
+   edit the Apache src/Configuration file manually.  If you do not have 
+   this file, copy Configuration.tmpl to Configuration.
+
+   For Apache 1.3.x add:
+
+      AddModule modules/php3/libphp3.a
+
+   For Apache 1.3.x don't do anything else.  Just add this line and then
+   run "./Configure" followed by "make".
+
+   For Apache 1.2.x add:
+
+      Module php3_module mod_php3.o
+
+   For Apache 1.2.x you will also have to look in the libphp3.module file,
+   which was copied to the src directory. The EXTRA_LIBS line in the Apache
+   Configuration file needs to be set to use the same libs as specified on
+   the LIBS line in libphp3.module. You also need to make sure to add
+   "-L." to the beginning of the EXTRA_LIBS line.
+
+   So, as an example, your EXTRA_LIBS line might look like:
+
+	EXTRA_LIBS=-L. -lphp3 -lgdbm -ldb -L/usr/local/mysql/lib -lmysqlclient
+
+   NOTE: You should not enclose the EXTRA_LIBS line in double-quotes, as it
+   is in the libphp3.module file.
+
+   Also, look at the RULE_WANTHSREGEX setting in the libphp3.module file 
+   and set the WANTHSREGEX directive accordingly in your Configuration file.
+   This last step applies to versions of Apache prior to 1.3b3.
+
+   This is a bit of a hassle, but should serve as incentive to move to
+   Apache 1.3.x where this step has been eliminated.
+
+   Once you are satisfied with your Configuration settings, type: ./Configure
+   If you get errors, chances are that you forgot a library or made a typo
+   somewhere.  Re-edit Configuration and try again.  If it goes well,
+   type: make
+
+4. Setting up the server.
+   
+   You should now have a new httpd binary.  Shut down your existing server,
+   if you have one, and copy this new binary overtop of it.  Perhaps make
+   a backup of your previous one first.  Then edit your conf/srm.conf file
+   and add the line:
+
+      AddType application/x-httpd-php3 .php3
+
+   There is also an interesting feature which can be quite instructive and
+   helpful while debugging.  That is the option of having colour syntax
+   highlighting.  To enable this, add the following line:
+
+      AddType application/x-httpd-php3-source .phps
+
+   Any file ending in .phps will now be displayed with full colour syntax
+   highlighting instead of being executed.
+
+   When you are finished making changes to your srm.conf file, you can
+   start up your server.

+QNX4 Installation Notes
+-----------------------
+
+NOTE: General installation instructions are in the INSTALL file 
+
+
+1. To compile and test PHP3 you have to grab, compile and install:
+	- GNU dbm library or another db library;
+	- GNU bison (1.25 or later; 1.25 tested);
+	- GNU flex (any version supporting -o and -P options; 2.5.4 tested);
+	- GNU diffutils (any version supporting -w option; 2.7 tested);
+
+2. To use CVS version you may need also:
+	- GNU CVS (1.9 tested);
+	- GNU autoconf (2.12 tested);
+	- GNU m4 (1.3 or later preferable; 1.4 tested);
+
+3. To run configure define -lunix in command line:
+	LDFLAGS=-lunix ./configure
+
+4. To use Sybase SQL Anywhere define ODBC_QNX and CUSTOM_ODBC_LIBS in
+	command line and run configure with --with-custom-odbc:
+	CFLAGS=-DODBC_QNX LDFLAGS=-lunix CUSTOM_ODBC_LIBS="-ldblib -lodbc" ./configure --with-custom-odbc=/usr/lib/sqlany50
+   If you have SQL Anywhere version 5.5.00, then you have to add 
+	CFLAGS=-DSQLANY_BUG
+   to workaround its SQLFreeEnv() bug. Other versions has not been tested,
+   so try without this flag first.
+
+5. To build the Apache module, you may have to hardcode an include path for 
+   alloc.h in your Apache base directory:
+	- APACHE_DIRECTORY/src/httpd.h: 
+		change	#include "alloc.h"
+		to 		#include "APACHE_DIRECTORY/src/alloc.h"
+   Unless you want to use system regex library, you have to hardcode also
+   a path to regex.h:
+	- APACHE_DIRECTORY/src/conf.h:  
+		change  #include <regex.h>
+		to		#include "APACHE_DIRECTORY/src/regex/regex.h"
+   I don't know so far why this required for QNX, may be it is Watcom 
+   compiler problem.
+
+  If you building Apache module with SQL Anywhere support, you'll get
+  symbol conflict with BOOL. It is defined in Apache (httpd.h) and in 
+  SQL Anywhere (odbc.h). This has nothing to do with PHP, so you have to 
+  fix it yourself someway.
+
+6. With above precautions, it should compile as is and pass regression
+	tests completely:
+		make
+		make check
+		make install
+
+	Don't bother me unless you really sure you made	that all but it 
+	still doesn't work.

+Windows 95/NT Specific Notes on Compilation
+
+Windows compilation has only been tested with Microsoft Visual C++ 
+Version 5 Standard Edition.  The PHP executable has only had limited
+testing under Windows 95.  SAFE MODE and any User or Group functionality
+has not been ported/tested.
+
+-----------------------------------------------------------------------
+Compiling PHP with MSVC5
+
+There are three msvc workspaces provided with this distribution.  The one
+most people will use is php3.dsw.  This contains project files for two
+versions on PHP, one with mySQL compiled internaly, and one without (both
+have ODBC internaly compiled).  It also contains all the modules.
+
+The next workspace is php3extras.dsw.  This project contains the converter
+and a program called phpwatch, which is a simple program to watch debugger
+output under windows.  The 'socket' program is also available from the php
+site, which is a better alternative to phpwatch.
+
+The third workspace is php3sapi.dsw.  These projects are experimental and
+will probably not compile most of the time.  It contains preliminary work
+on the server api's for windows.
+
+-----------------------------------------------------------------------
+Base Configuration and Configuration Issues
+
+*The base configuration for the windows php version contains odbc
+ support.  Support for other database modules will be provided as external dll files.  
+*ODBC can be used to connect to many of the databases previously 
+supported by php (though they can still be compiled in if you have 
+the libraries!)  
+
+-----------------------------------------------------------------------
+Makefiles
+
+Be sure to edit any windows makefile and change the include directories
+to be appropriate for your system.
+
+-----------------------------------------------------------------------
+CGI Version
+
+The makefile for the cgi version of php is located in the win32 
+subdirectory of the php source tree.  This make file is specificaly
+for Visual C++ V5.
+
+-----------------------------------------------------------------------
+ISAPI/NSAPI/WSAPI/Apache Versions
+
+These versions are not yet working.  They are located in the php3sapi.dsw
+workspace.
+
+
+-----------------------------------------------------------------------
+Other Libraries
+
+See the php faq at php.net for information on where to obtain the various
+libraries needed to compile some modules.

+Configuration Issues
+--------------------
+* properly detect dbm routines when they're in libc
+* add the appropriate #define magic for memmove and friends (see
+  GNU autoconf info pages for details)
+* make it possible to disable support for some extensions (gd, dbm)
+* make it possible to build selected extensions so they are
+  dynamically-loadable
+
+Core Language Issues
+--------------------
+* go through PHP2's php.h and see how each special #define might be
+  applied/supported in PHP3
+* move Treatdata() to language-scanner.lex where hash_environment()
+  is called including a decision about priority of variables and moving
+  Treatdata() to use hash_add() instead of hash_update() for insertions
+  to the symbol table.
+* go through FIXME and XXX lines (egrep 'FIXME|XXX' *.[ch])
+* make lexer and parser thread-safe
+* verify that binary strings are handled correctly
+V don't evaluate truth expressions more than once
+V make unset() work on arrays (tricky)
+
+Core Functions
+--------------
+* go through all file functions and make sure they are opened in binary
+  mode in win32 if needed (ie copy)
+* go through all functions and look at PHP_SAFE_MODE issues
+* have a look at return codes of fsockopen() function - we should
+  probably RETURN_FALSE and then set an error code somewhere (Rasmus)
+* go through FIXME and XXX lines (egrep 'FIXME|XXX' functions/*.[ch])
+* add user-level flock() implementation to let people lock and unlock files 
+* add "'" modifier to sprintf to group thousands by comma
+* Add an improved eval() that doesn't "leak"
+? sorting of objects with a user-defined comparison function (like Perl)
+  (this shouldn't be expected before 3.1, if at all).
+
+
+Extensions
+----------
+* add version strings for all extensions
+* Oracle persistent connections
+U gd support for windows
+* Illustra support (APIS)
+? CQL++ support (http://www.cql.com/)
+? GNU SQL support (does anybody actually use this?)
+? DB2 support (http://www.sleepycat.com/)
+? Shore support (http://www.cs.wisc.edu/shore/)
+? PGP Interface (use PGPlib?)
+? more Perl-like regex handling?
+
+Server Support
+--------------
+P ISAPI (Shane)
+  * process cookies
+  * blocking functions
+  * make sure it's Microsoft-clean so it can be used with other ISAPI
+    implementations
+* WSAPI
+* NSAPI
+  * process cookies
+  * check POST method handling code
+  * use Netscape memory allocation inside emalloc() and company
+* FastCGI support - see http://fastcgi.idle.com/
+
+Win32 Specific
+--------------
+* implement some kind of syslog->file log support for win95.
+* change all file open/read/write functions from c library to win32 
+  api file functions.  The win32 api functions handle both disk files
+  and network files.  This will allow include and require to use http
+  or ftp files as the unix version does, and do away with my
+  workaround to support this.  (3.1?)
+* implement symlinks via windows shell links (shortcuts).  This will
+  work only at the script level and is not a c language level port.
+
+Testing
+-------
+* truss/strace a typical PHP request and see if there are some system
+  calls that could be optimized out
+* verify that regression tests exist for all core functions
+
+Miscellaneous
+-------------
+* remove hard-coded compilation options
+? locale issues - funny things happen in PHP2 when the locale is set to
+  use , instead of . as the decimal seperator.  ie. 1.5+1.5 = 1
+? SSI->PHP3 conversion script
+? SQL-based access logging (start with examples/log-*.php3)

+- Persistant per-process scripting
+
+  Apache 1.3 has added things that makes this much easier than before.
+  The module structure now contains a child_init hook and a child_exit 
+  hook where you can register functions to be called when an httpd
+  process starts up and when one shuts down (due to MaxRequestsPerChild 
+  or a Kill).  The only real trick now is to come up with some sort of
+  syntax for specifying what to do from the child_init call and the
+  child_exit call.
+
+  One idea is to be able to add a <PHP>...</PHP> block to the Apache
+  httpd.conf file which would somehow define a series of PHP statements
+  to be executed from the child_* calls.  One for startup and another
+  block for shutdown.  These blocks would work with the per-process
+  memory pool, so any variables initialized here would have a lifespan
+  equal to that of the httpd process.  Basically request-spanning
+  global variables.

+* Bundle some nice classes (like Bjørn's graphing class)

+* Clean up API and modules to make .so modules portable across CGI and server

+* dbm cleanup (don't arbitrarily pick, and support multiple concurrent formats)

+* COM implementation so php can be used as an asp language (cant find any docs
+  on how this is done though)
+* Clean up the file structure so the top-level directory isn't such a mess.
+* Bring the module concept to maturity: use libtool and make it
+  possible to decide at compile time whether you want to compile a
+  module statically or dynamically.  Remove the distinction between
+  the stuff currently in dl/ and functions/.
+* a way of letting each module specify its options, so ini file options and
+  Apache directives can be set up from the same specification.
+V Make it possible to declare smarter user functions: (done in 3.0)
+  - Optional parameters
+  - Parameters that are forced/prefered by reference
+* Make object parsing more general, and allow nested arrays/objects with
+  unlimited levels.
+V Make it possible to copy references of variables.
+* data tainting (like perl -T)
+* multi-dimensional array support in GET/POST/COOKIE handling code
+* Persistent functions and classes

+V COM automation support for Win32

+----------------- 
+
+1. Function Prototype
+
+   All functions look like this:
+
+       void php3_foo(INTERNAL_FUNCTION_PARAMETERS) {
+
+       }
+
+   Even if your function doesn't take any arguments, this is how it is
+   called.
+
+-----------------
+
+2. Function Arguments
+
+   Arguments are always of type pval.  This type contains a union which
+   has the actual type of the argument.  So, if your function takes two
+   arguments, you would do something like the following at the top of your
+   function:
+
+       pval *arg1, *arg2;
+       if (ARG_COUNT(ht) != 2 || getParameters(ht,2,&arg1,&arg2)==FAILURE) {
+           WRONG_PARAM_COUNT;
+       }
+
+   NOTE: Arguments can be passed either by value or by reference. In both
+   cases you will need to pass &(pval *) to getParameters. If you want to
+   check if the n'th parameter was sent to you by reference or not, you can
+   use the function, ParameterPassedByReference(ht,n). It will return either
+   1 or 0.
+
+   When you change any of the passed parameters, whether they are sent by
+   reference or by value, you can either start over with the parameter by
+   calling pval_destructor on it, or if it's an ARRAY you want to add to,
+   you can use functions similar to the ones in internal_functions.h which
+   manipulate return_value as an ARRAY.
+
+   Also if you change a parameter to IS_STRING make sure you first assign
+   the new estrdup'ed string and the string length, and only later change the
+   type to IS_STRING. If you change the string of a parameter which already
+   IS_STRING or IS_ARRAY you should run pval_destructor on it first.
+   
+-----------------
+
+3. Variable number of function arguments
+
+   A function can take a variable number of arguments.  If your function can
+   take either 2 or 3 arguments, use the following:
+
+       pval *arg1, *arg2, *arg3;
+       int arg_count = ARG_COUNT(ht);
+
+       if (arg_count<2 || arg_count>3 ||
+           getParameters(ht,arg_count,&arg1,&arg2,&arg3)==FAILURE) {
+           WRONG_PARAM_COUNT;
+       }
+
+------------------
+
+4. Using the function arguments
+
+   The type of each argument is stored in the pval type field:
+
+
+   This type can be any of the following:
+
+       IS_STRING             String
+       IS_DOUBLE             Double-precision floating point
+       IS_LONG               Long
+       IS_ARRAY              Array
+
+       IS_EMPTY              ??
+       IS_USER_FUNCTION      ??
+       IS_INTERNAL_FUNCTION  ?? (if some of these cannot be passed to a
+                                 function - delete)
+       IS_CLASS              ??
+       IS_OBJECT             ??
+       
+   If you get an argument of one type and would like to use it as another,
+   or if you just want to force the argument to be of a certain type, you
+   can use one of the following conversion functions:
+
+       convert_to_long(arg1);
+       convert_to_double(arg1);
+       convert_to_string(arg1); 
+       convert_to_boolean_long(arg1);    If the string is "" or "0" it
+                                         becomes 0, 1 otherwise
+       convert_string_to_number(arg1);   Converts string to either LONG or
+                                         DOUBLE depending on string
+
+   These function all do in-place conversion.  They do not return anything.
+
+   The actual argument is stored in a union.  
+
+   For type IS_STRING, use arg1->value.str.val
+            IS_LONG        arg1->value.lval
+            IS_DOUBLE      arg1->value.dval
+ 
+-------------------
+
+5. Memory management in functions
+
+   Any memory needed by a function should be allocated with either emalloc()
+   or estrdup().  These are memory handling abstraction functions that look
+   and smell like the normal malloc() and strdup() functions.  Memory should
+   be freed with efree().
+
+   There are two kinds of memory in this program. Memory which is returned
+   to the parser in a variable and memory which you need for temporary
+   storage in your internal function.  When you assign a string to a
+   variable which is returned to the parser you need to make sure you first
+   allocate the memory with either emalloc or estrdup.  This memory
+   should NEVER be freed by you, unless you later, in the same function
+   overwrite your original assignment (this kind of programming practice is
+   not good though).
+
+   For any temporary/permanent memory you need in your functions/library you
+   should use the three emalloc(), estrdup(), and efree() functions. They
+   behave EXACTLY like their counterpart functions. Anything you emalloc()
+   or estrdup() you have to efree() at some point or another, unless it's
+   supposed to stick around until the end of the program, otherwise there
+   will be a memory leak. The meaning of "the functions behave exactly like
+   their counterparts" is if you efree() something which was not
+   emalloc()'ed nor estrdup()'ed you might get a segmentation fault. So
+   please take care and free all of your wasted memory. One of the biggest
+   improvements in PHP 3.0 will hopefully be the memory management.
+
+   If you compile with "-DDEBUG", PHP3 will print out a list of all
+   memory that was allocated using emalloc() and estrdup() but never
+   freed with efree() when it is done running the specified script.
+
+-------------------
+
+6. Setting variables in the symbol table
+
+   A number of macros are available which make it easier to set a variable
+   in the symbol table:
+
+       SET_VAR_STRING(name,value) **
+       SET_VAR_DOUBLE(name,value)
+       SET_VAR_LONG(name,value)
+
+   ** Be careful here.  The value part must be malloc'ed manually because
+      the memory management code will try to free this pointer later.  Do
+      not pass statically allocated memory into a SET_VAR_STRING
+
+  Symbol tables in PHP 3.0 are implemented as hash tables.  At any given time,
+  &symbol_table is a pointer to the 'main' symbol table, and active_symbol_table
+  points to the currently active symbol table (these may be identical like in
+  startup, or different, if you're inside a function).
+  
+  The following examples use 'active_symbol_table'.  You should replace it with
+  &symbol_table if you specifically want to work with the 'main' symbol table.
+  Also, the same funcions may be applied to arrays, as explained below.
+  
+  * To check whether a variable named $foo already exists in a symbol table:
+    if (hash_exists(active_symbol_table,"foo",sizeof("foo"))) { exists... }
+    else { doesn't exist }
+  
+  * If you also need to get the type of the variable, you can use:
+    hash_find(active_symbol_table,"foo",sizeof("foo"),&pvalue);
+    check(pvalue.type);
+  
+  Arrays in PHP 3.0 are implemented using the same hashtables as symbol tables.
+  This means the two above functions can also be used to check variables
+  inside arrays.
+
+  If you want to define a new array in a symbol table, you should do this:
+
+      1.  Possibly check it exists and abort, using hash_exists()
+          or hash_find().
+      2.  Code:
+  
+      pval arr;
+  
+      if (array_init(&arr) == FAILURE) { failed... };
+      hash_update(active_symbol_table,"foo",sizeof("foo"),&arr,sizeof(pval),NULL);
+  
+  This code declares a new array, named $foo, in the active symbol table.
+  This array is empty.
+  
+  Here's how to add new entries to it:
+  
+      pval entry;
+  
+      entry.type = IS_LONG;
+      entry.value.lval = 5;
+  
+      hash_update(arr.value.ht,"bar",sizeof("bar"),&entry,sizeof(pval),NULL); /* defines $foo["bar"] = 5 */
+      hash_index_update(arr.value.ht,7,&entry,sizeof(pval),NULL); /* defines $foo[7] = 5 */
+      hash_next_index_insert(arr.value.ht,&entry,sizeof(pval),NULL); /* defines the next free place in $foo[],
+                                                                         * $foo[8], to be 5 (works like php2)
+                                                                         */
+  
+  If you'd like to modify a value that you inserted to a hash, you must first retreive it from the hash.  To
+  prevent that overhead, you can supply a pval ** to the hash add function, and it'll be updated with the
+  pval * address of the inserted element inside the hash.  If that value is NULL (like in all of the
+  above examples) - that parameter is ignored.
+
+  hash_next_index_insert() works more or less using the same logic
+  "$foo[] = bar;" works in PHP 2.0.
+
+  If you are building an array to return from a function, you can initialize
+  the array just like above by doing:
+
+    if (array_init(return_value) == FAILURE) { failed...; }
+
+  and then adding values with the helper functions:
+
+    add_next_index_long(return_value,long_value);
+    add_next_index_double(return_value,double_value);
+    add_next_index_string(return_value,estrdup(string_value));
+  
+  Of course, if the adding isn't done right after the array
+  initialization, you'd probably have to look for the array first:
+  
+    pval *arr;
+  
+    if (hash_find(active_symbol_table,"foo",sizeof("foo"),(void **)&arr)==FAILURE) { can't find... }
+    else { use arr->value.ht... }
+  
+  Note that hash_find receives a pointer to a pval pointer, and
+  not a pval pointer.
+  
+  Just about any hash function returns SUCCESS or FAILURE (except for
+  hash_exists() that returns a boolean truth value).
+    
+-------------------
+
+7. Returning 'simple' values from functions (integers, floats or strings)
+
+   A number of macros are available to make it easier to return things from
+   functions:
+
+   These set the return value and return from the function:
+
+   RETURN_FALSE
+   RETURN_TRUE
+   RETURN_LONG(l)
+   RETURN_STRING(s,dup)        If dup is true, duplicates the string
+   RETURN_STRINGL(s,l,dup)     Return string (s) specifying length (l).
+   RETURN_DOUBLE(d)
+
+   These only set the return value:
+
+   RETVAL_FALSE
+   RETVAL_TRUE
+   RETVAL_LONG(l)
+   RETVAL_STRING(s,dup)       If dup is true, duplicates the string
+   RETVAL_STRINGL(s,l,dup)    Return string (s) specifying length (l).
+   RETVAL_DOUBLE(d)
+
+   The string macros above will all estrdup() the passed 's' argument,
+   so you can safely free the argument after calling the macro, or
+   alternatively use statically allocated memory.
+
+   If your function returns boolean success/error responses, always use
+   RETURN_TRUE and RETURN_FALSE respectively.
+
+-------------------
+
+8. Returning 'complex' values from functions (arrays or objects)
+
+   Your function can also return a complex data type such as an object
+   or an array.
+
+   Returning an object:
+
+   1. Call object_init(return_value).
+   2. Fill it up with values:
+
+   add_property_long(return_value,property_name,l)			Add a property named 'property_name', of type long, equals to 'l'
+   add_property_double(return_value,property_name,d)		Same, only a double
+   add_property_string(return_value,property_name,str)		Same, only a string
+   add_property_stringl(return_value,property_name,str,l)	Add a property named 'property_name', of type string, string is 'str' with length 'l'
+
+   3. Possibly, register functions for this object.  In order to
+      obtain values from the object, the function would have to fetch
+      "this" from the active_symbol_table.  Its type should be IS_OBJECT,
+      and it's basically a regular hash table (i.e., you can use regular
+      hash functions on .value.ht).  The actual registration of the
+      function can be done using:
+   
+   add_method(return_value,function_name,function_ptr)
+   
+   
+   Returning an array:
+
+   1.  Call array_init(return_value).
+   2.  Fill it up with values:
+
+   add_assoc_long(return_value,key,l)				add associative entry with key 'key' and long value 'l'
+   add_assoc_double(return_value,key,d)		
+   add_assoc_string(return_value,key,str)
+   add_assoc_stringl(return_value,key,str,length)	specify the string length
+
+   add_index_long(return_value,index,l)				add entry in index 'index' with long value 'l'
+   add_index_double(return_value,index,d)
+   add_index_string(return_value,index,str)
+   add_index_stringl(return_value,index,str,length)  specify the string length
+
+   add_next_index_long(return_value,l)				add an array entry in the next free offset with long value 'l'
+   add_next_index_double(return_value,d)
+   add_next_index_string(return_value,str)
+   add_next_index_stringl(return_value,str,length)	specify the string length
+
+-------------------
+
+9. Using the resource list
+
+   PHP 3.0 has a standard way of dealing with various types of resources,
+   that replaces all of the local linked lists in PHP 2.0.
+
+   Available functions:
+
+   php3_list_insert(ptr, type)      returns the 'id' of the newly inserted resource
+   php3_list_delete(id)             delete the resource with the specified id
+   php3_list_find(id,*type)         returns the pointer of the resource with the specified id, updates 'type' to the resource's type
+
+   Typically, these functions are used for SQL drivers but they can be
+   used for anything else, and are used, for instance, for maintaining
+   file descriptors.
+
+   Typical list code would look like this:
+
+	Adding a new resource:
+
+		RESOURCE *resource;
+
+		...allocate memory for resource and acquire resource...
+		/* add a new resource to the list */
+		return_value->value.lval = php3_list_insert((void *) resource, LE_RESOURCE_TYPE);
+		return_value->type = IS_LONG;
+
+	Using an existing resource:
+
+		pval *resource_id;
+		RESOURCE *resource;
+		int type;
+
+		convert_to_long(resource_id);
+		resource = php3_list_find(resource_id->value.lval, &type);
+		if (type != LE_RESOURCE_TYPE) {
+			php3_error(E_WARNING,"resource index %d has the wrong type",resource_id->value.lval);
+			RETURN_FALSE;
+		}
+		...use resource...
+
+	Deleting an existing resource:
+
+		pval *resource_id;
+		RESOURCE *resource;
+		int type;
+
+		convert_to_long(resource_id);
+		php3_list_delete(resource_id->value.lval);
+   
+
+   The resource types should be registered in php3_list.h, in enum
+   list_entry_type.  In addition, one should add shutdown code for any
+   new resource type defined, in list.c's list_entry_destructor() (even if
+   you don't have anything to do on shutdown, you must add an empty case).
+
+-------------------
+
+10. Using the persistent resource table
+
+   PHP 3.0 has a standard way of storing persistent resources (i.e.,
+   resources that are kept in between hits).  The first module to use
+   this feature was the MySQL module, and mSQL followed it, so one can
+   get the general impression of how a persistent resource should be
+   used by reading mysql.c.  The functions you should look at are:
+   php3_mysql_do_connect()
+   php3_mysql_connect()
+   php3_mysql_pconnect()
+
+   The general idea of persistence modules is this:
+   1.  Code all of your module to work with the regular resource list
+       mentioned in section (9).
+   2.  Code extra connect functions that check if the resource already
+       exists in the persistent resource list.  If it does, register it
+       as in the regular resource list as a pointer to the persistent
+       resource list (because of 1., the rest of the code
+       should work immediately).  If it doesn't, then create it, add it
+       to the persistent resource list AND add a pointer to it from the
+       regular resource list, so all of the code would work since it's
+       in the regular resource list, but on the next connect, the
+       resource would be found in the persistent resource list and be
+       used without having to recreate it.
+       You should register these resources with a different type (e.g.
+       LE_MYSQL_LINK for non-persistent link and LE_MYSQL_PLINK for
+       a persistent link).
+
+   If you read mysql.c, you'll notice that except for the more complex
+   connect function, nothing in the rest of the module has to be changed.
+   
+   The very same interface exists for the regular resource list and the
+   persistent resource list, only 'list' is replaced with 'plist':
+
+   php3_plist_insert(ptr, type)      returns the 'id' of the newly inserted resource
+   php3_plist_delete(id)             delete the resource with the specified id
+   php3_plist_find(id,*type)         returns the pointer of the resource with the specified id, updates 'type' to the resource's type
+
+   However, it's more than likely that these functions would prove
+   to be useless for you when trying to implement a persistent module.
+   Typically, one would want to use the fact that the persistent resource
+   list is really a hash table.  For instance, in the MySQL/mSQL modules,
+   when there's a pconnect() call (persistent connect), the function
+   builds a string out of the host/user/passwd that were passed to the
+   function, and hashes the SQL link with this string as a key.  The next
+   time someone calls a pconnect() with the same host/user/passwd, the
+   same key would be generated, and the function would find the SQL link
+   in the persistent list.
+
+   Until further documented, you should look at mysql.c or msql.c to
+   see how one should use the plist's hash table abilities.
+
+   One important thing to note:  resources going into the persistent
+   resource list must *NOT* be allocated with PHP's memory manager, i.e.,
+   they should NOT be created with emalloc(), estrdup(), etc.  Rather,
+   one should use the regular malloc(), strdup(), etc.  The reason for
+   this is simple - at the end of the request (end of the hit), every
+   memory chunk that was allocated using PHP's memory manager is deleted.
+   Since the persistent list isn't supposed to be erased at the end
+   of a request, one mustn't use PHP's memory manager for allocating
+   resources that go to it.
+
+   Shutting down persistent resources:  
+   
+   When you register resource that's going to be in the persistent list,
+   you should add destructors to it both in the non-persistent list
+   and in the persistent list.
+   The destructor in the non-persistent list destructor shouldn't do anything.
+   The one in the persistent list destructor should properly free any
+   resources obtained by that type (e.g. memory, SQL links, etc).  Just like
+   with the non-persistent resources, you *MUST* add destructors for every
+   resource, even it requires no destructotion and the destructor would
+   be empty.
+   Remember, since emalloc() and friends aren't to be used in conjunction
+   with the persistent list, you mustn't use efree() here either.
+
+-------------------
+
+11. Adding runtime configuration directives
+
+Many of the features of PHP3 can be configured at runtime.  These
+configuration directives can appear in either the designated php3.ini
+file, or in the case of the Apache module version in the Apache .conf
+files.  The advantage of having them in the Apache .conf files is that
+they can be configured on a per-directory basis.  This means that one
+directory may have a certain safemodeexecdir for example, while another
+directory may have another.  This configuration granularity is especially
+handy when a server supports multiple virtual hosts.
+
+The steps required to add a new directive:
+
+ 1. Add directive to php3_ini_structure struct in mod_php3.h. 
+    
+ 2. In main.c, edit the php3_module_startup function and add the
+    appropriate cfg_get_string() or cfg_get_long() call.
+
+ 3. Add the directive, restrictions and a comment to the php3_commands
+    structure in mod_php3.c.  Note the restrictions part.  RSRC_CONF are
+    directives that can only be present in the actual Apache .conf files.
+    Any OR_OPTIONS directives can be present anywhere, include normal
+    .htaccess files.
+
+ 4. In either php3take1handler() or php3flaghandler() add the appropriate
+    entry for your directive.
+
+ 5. In the configuration section of the _php3_info() function in
+    functions/info.c you need to add your new directive.
+
+ 6. And last, you of course have to use your new directive somewhere.
+    It will be addressable as php3_ini.directive

+alpha3.4 release.
+Thu Mar 17 23:17:18 EST 1994
+henry@zoo.toronto.edu
+
+See WHATSNEW for change listing.
+
+installation notes:
+--------
+Read the comments at the beginning of Makefile before running.
+
+Utils.h contains some things that just might have to be modified on
+some systems, as well as a nested include (ugh) of <assert.h>.
+
+The "fake" directory contains quick-and-dirty fakes for some header
+files and routines that old systems may not have.  Note also that
+-DUSEBCOPY will make utils.h substitute bcopy() for memmove().
+
+After that, "make r" will build regcomp.o, regexec.o, regfree.o,
+and regerror.o (the actual routines), bundle them together into a test
+program, and run regression tests on them.  No output is good output.
+
+"make lib" builds just the .o files for the actual routines (when
+you're happy with testing and have adjusted CFLAGS for production),
+and puts them together into libregex.a.  You can pick up either the
+library or *.o ("make lib" makes sure there are no other .o files left
+around to confuse things).
+
+Main.c, debug.c, split.c are used for regression testing but are not part
+of the RE routines themselves.
+
+Regex.h goes in /usr/include.  All other .h files are internal only.

+New in alpha3.4:  The complex bug alluded to below has been fixed (in a
+slightly kludgey temporary way that may hurt efficiency a bit; this is
+another "get it out the door for 4.4" release).  The tests at the end of
+the tests file have accordingly been uncommented.  The primary sign of
+the bug was that something like a?b matching ab matched b rather than ab.
+(The bug was essentially specific to this exact situation, else it would
+have shown up earlier.)
+
+New in alpha3.3:  The definition of word boundaries has been altered
+slightly, to more closely match the usual programming notion that "_"
+is an alphabetic.  Stuff used for pre-ANSI systems is now in a subdir,
+and the makefile no longer alludes to it in mysterious ways.  The
+makefile has generally been cleaned up some.  Fixes have been made
+(again!) so that the regression test will run without -DREDEBUG, at
+the cost of weaker checking.  A workaround for a bug in some folks'
+<assert.h> has been added.  And some more things have been added to
+tests, including a couple right at the end which are commented out
+because the code currently flunks them (complex bug; fix coming).
+Plus the usual minor cleanup.
+
+New in alpha3.2:  Assorted bits of cleanup and portability improvement
+(the development base is now a BSDI system using GCC instead of an ancient
+Sun system, and the newer compiler exposed some glitches).  Fix for a
+serious bug that affected REs using many [] (including REG_ICASE REs
+because of the way they are implemented), *sometimes*, depending on
+memory-allocation patterns.  The header-file prototypes no longer name
+the parameters, avoiding possible name conflicts.  The possibility that
+some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
+now handled gracefully.  "uchar" is no longer used as an internal type
+name (too many people have the same idea).  Still the same old lousy
+performance, alas.
+
+New in alpha3.1:  Basically nothing, this release is just a bookkeeping
+convenience.  Stay tuned.
+
+New in alpha3.0:  Performance is no better, alas, but some fixes have been
+made and some functionality has been added.  (This is basically the "get
+it out the door in time for 4.4" release.)  One bug fix:  regfree() didn't
+free the main internal structure (how embarrassing).  It is now possible
+to put NULs in either the RE or the target string, using (resp.) a new
+REG_PEND flag and the old REG_STARTEND flag.  The REG_NOSPEC flag to
+regcomp() makes all characters ordinary, so you can match a literal
+string easily (this will become more useful when performance improves!).
+There are now primitives to match beginnings and ends of words, although
+the syntax is disgusting and so is the implementation.  The REG_ATOI
+debugging interface has changed a bit.  And there has been considerable
+internal cleanup of various kinds.
+
+New in alpha2.3:  Split change list out of README, and moved flags notes
+into Makefile.  Macro-ized the name of regex(7) in regex(3), since it has
+to change for 4.4BSD.  Cleanup work in engine.c, and some new regression
+tests to catch tricky cases thereof.
+
+New in alpha2.2:  Out-of-date manpages updated.  Regerror() acquires two
+small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
+in my own test program and might be useful to others for similar purposes.
+The regression test will now compile (and run) without REDEBUG.  The
+BRE \$ bug is fixed.  Most uses of "uchar" are gone; it's all chars now.
+Char/uchar parameters are now written int/unsigned, to avoid possible
+portability problems with unpromoted parameters.  Some unsigned casts have
+been introduced to minimize portability problems with shifting into sign
+bits.
+
+New in alpha2.1:  Lots of little stuff, cleanup and fixes.  The one big
+thing is that regex.h is now generated, using mkh, rather than being
+supplied in the distribution; due to circularities in dependencies,
+you have to build regex.h explicitly by "make h".  The two known bugs
+have been fixed (and the regression test now checks for them), as has a
+problem with assertions not being suppressed in the absence of REDEBUG.
+No performance work yet.
+
+New in alpha2:  Backslash-anything is an ordinary character, not an
+error (except, of course, for the handful of backslashed metacharacters
+in BREs), which should reduce script breakage.  The regression test
+checks *where* null strings are supposed to match, and has generally
+been tightened up somewhat.  Small bug fixes in parameter passing (not
+harmful, but technically errors) and some other areas.  Debugging
+invoked by defining REDEBUG rather than not defining NDEBUG.
+
+New in alpha+3:  full prototyping for internal routines, using a little
+helper program, mkh, which extracts prototypes given in stylized comments.
+More minor cleanup.  Buglet fix:  it's CHAR_BIT, not CHAR_BITS.  Simple
+pre-screening of input when a literal string is known to be part of the
+RE; this does wonders for performance.
+
+New in alpha+2:  minor bits of cleanup.  Notably, the number "32" for the
+word width isn't hardwired into regexec.c any more, the public header
+file prototypes the functions if __STDC__ is defined, and some small typos
+in the manpages have been fixed.
+
+New in alpha+1:  improvements to the manual pages, and an important
+extension, the REG_STARTEND option to regexec().

+.SH DESCRIPTION
+These routines implement POSIX 1003.2 regular expressions (``RE''s);
+see
+.ZR .
+.I Regcomp
+compiles an RE written as a string into an internal form,
+.I regexec
+matches that internal form against a string and reports results,
+.I regerror
+transforms error codes from either into human-readable messages,
+and
+.I regfree
+frees any dynamically-allocated storage used by the internal form
+of an RE.
+.PP
+The header
+.I <regex.h>
+declares two structure types,
+.I regex_t
+and
+.IR regmatch_t ,
+the former for compiled internal forms and the latter for match reporting.
+It also declares the four functions,
+a type
+.IR regoff_t ,
+and a number of constants with names starting with ``REG_''.
+.PP
+.I Regcomp
+compiles the regular expression contained in the
+.I pattern
+string,
+subject to the flags in
+.IR cflags ,
+and places the results in the
+.I regex_t
+structure pointed to by
+.IR preg .
+.I Cflags
+is the bitwise OR of zero or more of the following flags:
+.IP REG_EXTENDED \w'REG_EXTENDED'u+2n
+Compile modern (``extended'') REs,
+rather than the obsolete (``basic'') REs that
+are the default.
+.IP REG_BASIC
+This is a synonym for 0,
+provided as a counterpart to REG_EXTENDED to improve readability.
+.IP REG_NOSPEC
+Compile with recognition of all special characters turned off.
+All characters are thus considered ordinary,
+so the ``RE'' is a literal string.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+REG_EXTENDED and REG_NOSPEC may not be used
+in the same call to
+.IR regcomp .
+.IP REG_ICASE
+Compile for matching that ignores upper/lower case distinctions.
+See
+.ZR .
+.IP REG_NOSUB
+Compile for matching that need only report success or failure,
+not what was matched.
+.IP REG_NEWLINE
+Compile for newline-sensitive matching.
+By default, newline is a completely ordinary character with no special
+meaning in either REs or strings.
+With this flag,
+`[^' bracket expressions and `.' never match newline,
+a `^' anchor matches the null string after any newline in the string
+in addition to its normal function,
+and the `$' anchor matches the null string before any newline in the
+string in addition to its normal function.
+.IP REG_PEND
+The regular expression ends,
+not at the first NUL,
+but just before the character pointed to by the
+.I re_endp
+member of the structure pointed to by
+.IR preg .
+The
+.I re_endp
+member is of type
+.IR const\ char\ * .
+This flag permits inclusion of NULs in the RE;
+they are considered ordinary characters.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+When successful,
+.I regcomp
+returns 0 and fills in the structure pointed to by
+.IR preg .
+One member of that structure
+(other than
+.IR re_endp )
+is publicized:
+.IR re_nsub ,
+of type
+.IR size_t ,
+contains the number of parenthesized subexpressions within the RE
+(except that the value of this member is undefined if the
+REG_NOSUB flag was used).
+If
+.I regcomp
+fails, it returns a non-zero error code;
+see DIAGNOSTICS.
+.PP
+.I Regexec
+matches the compiled RE pointed to by
+.I preg
+against the
+.IR string ,
+subject to the flags in
+.IR eflags ,
+and reports results using
+.IR nmatch ,
+.IR pmatch ,
+and the returned value.
+The RE must have been compiled by a previous invocation of
+.IR regcomp .
+The compiled form is not altered during execution of
+.IR regexec ,
+so a single compiled RE can be used simultaneously by multiple threads.
+.PP
+By default,
+the NUL-terminated string pointed to by
+.I string
+is considered to be the text of an entire line, minus any terminating
+newline.
+The
+.I eflags
+argument is the bitwise OR of zero or more of the following flags:
+.IP REG_NOTBOL \w'REG_STARTEND'u+2n
+The first character of
+the string
+is not the beginning of a line, so the `^' anchor should not match before it.
+This does not affect the behavior of newlines under REG_NEWLINE.
+.IP REG_NOTEOL
+The NUL terminating
+the string
+does not end a line, so the `$' anchor should not match before it.
+This does not affect the behavior of newlines under REG_NEWLINE.
+.IP REG_STARTEND
+The string is considered to start at
+\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_so\fR
+and to have a terminating NUL located at
+\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_eo\fR
+(there need not actually be a NUL at that location),
+regardless of the value of
+.IR nmatch .
+See below for the definition of
+.IR pmatch
+and
+.IR nmatch .
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+Note that a non-zero \fIrm_so\fR does not imply REG_NOTBOL;
+REG_STARTEND affects only the location of the string,
+not how it is matched.
+.PP
+See
+.ZR
+for a discussion of what is matched in situations where an RE or a
+portion thereof could match any of several substrings of
+.IR string .
+.PP
+Normally,
+.I regexec
+returns 0 for success and the non-zero code REG_NOMATCH for failure.
+Other non-zero error codes may be returned in exceptional situations;
+see DIAGNOSTICS.
+.PP
+If REG_NOSUB was specified in the compilation of the RE,
+or if
+.I nmatch
+is 0,
+.I regexec
+ignores the
+.I pmatch
+argument (but see below for the case where REG_STARTEND is specified).
+Otherwise,
+.I pmatch
+points to an array of
+.I nmatch
+structures of type
+.IR regmatch_t .
+Such a structure has at least the members
+.I rm_so
+and
+.IR rm_eo ,
+both of type
+.I regoff_t
+(a signed arithmetic type at least as large as an
+.I off_t
+and a
+.IR ssize_t ),
+containing respectively the offset of the first character of a substring
+and the offset of the first character after the end of the substring.
+Offsets are measured from the beginning of the
+.I string
+argument given to
+.IR regexec .
+An empty substring is denoted by equal offsets,
+both indicating the character following the empty substring.
+.PP
+The 0th member of the
+.I pmatch
+array is filled in to indicate what substring of
+.I string
+was matched by the entire RE.
+Remaining members report what substring was matched by parenthesized
+subexpressions within the RE;
+member
+.I i
+reports subexpression
+.IR i ,
+with subexpressions counted (starting at 1) by the order of their opening
+parentheses in the RE, left to right.
+Unused entries in the array\(emcorresponding either to subexpressions that
+did not participate in the match at all, or to subexpressions that do not
+exist in the RE (that is, \fIi\fR\ > \fIpreg\fR\->\fIre_nsub\fR)\(emhave both
+.I rm_so
+and
+.I rm_eo
+set to \-1.
+If a subexpression participated in the match several times,
+the reported substring is the last one it matched.
+(Note, as an example in particular, that when the RE `(b*)+' matches `bbb',
+the parenthesized subexpression matches each of the three `b's and then
+an infinite number of empty strings following the last `b',
+so the reported substring is one of the empties.)
+.PP
+If REG_STARTEND is specified,
+.I pmatch
+must point to at least one
+.I regmatch_t
+(even if
+.I nmatch
+is 0 or REG_NOSUB was specified),
+to hold the input offsets for REG_STARTEND.
+Use for output is still entirely controlled by
+.IR nmatch ;
+if
+.I nmatch
+is 0 or REG_NOSUB was specified,
+the value of
+.IR pmatch [0]
+will not be changed by a successful
+.IR regexec .
+.PP
+.I Regerror
+maps a non-zero
+.I errcode
+from either
+.I regcomp
+or
+.I regexec
+to a human-readable, printable message.
+If
+.I preg
+is non-NULL,
+the error code should have arisen from use of
+the
+.I regex_t
+pointed to by
+.IR preg ,
+and if the error code came from
+.IR regcomp ,
+it should have been the result from the most recent
+.I regcomp
+using that
+.IR regex_t .
+.RI ( Regerror
+may be able to supply a more detailed message using information
+from the
+.IR regex_t .)
+.I Regerror
+places the NUL-terminated message into the buffer pointed to by
+.IR errbuf ,
+limiting the length (including the NUL) to at most
+.I errbuf_size
+bytes.
+If the whole message won't fit,
+as much of it as will fit before the terminating NUL is supplied.
+In any case,
+the returned value is the size of buffer needed to hold the whole
+message (including terminating NUL).
+If
+.I errbuf_size
+is 0,
+.I errbuf
+is ignored but the return value is still correct.
+.PP
+If the
+.I errcode
+given to
+.I regerror
+is first ORed with REG_ITOA,
+the ``message'' that results is the printable name of the error code,
+e.g. ``REG_NOMATCH'',
+rather than an explanation thereof.
+If
+.I errcode
+is REG_ATOI,
+then
+.I preg
+shall be non-NULL and the
+.I re_endp
+member of the structure it points to
+must point to the printable name of an error code;
+in this case, the result in
+.I errbuf
+is the decimal digits of
+the numeric value of the error code
+(0 if the name is not recognized).
+REG_ITOA and REG_ATOI are intended primarily as debugging facilities;
+they are extensions,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+Be warned also that they are considered experimental and changes are possible.
+.PP
+.I Regfree
+frees any dynamically-allocated storage associated with the compiled RE
+pointed to by
+.IR preg .
+The remaining
+.I regex_t
+is no longer a valid compiled RE
+and the effect of supplying it to
+.I regexec
+or
+.I regerror
+is undefined.
+.PP
+None of these functions references global variables except for tables
+of constants;
+all are safe for use from multiple threads if the arguments are safe.
+.SH IMPLEMENTATION CHOICES
+There are a number of decisions that 1003.2 leaves up to the implementor,
+either by explicitly saying ``undefined'' or by virtue of them being
+forbidden by the RE grammar.
+This implementation treats them as follows.
+.PP
+See
+.ZR
+for a discussion of the definition of case-independent matching.
+.PP
+There is no particular limit on the length of REs,
+except insofar as memory is limited.
+Memory usage is approximately linear in RE size, and largely insensitive
+to RE complexity, except for bounded repetitions.
+See BUGS for one short RE using them
+that will run almost any system out of memory.
+.PP
+A backslashed character other than one specifically given a magic meaning
+by 1003.2 (such magic meanings occur only in obsolete [``basic''] REs)
+is taken as an ordinary character.
+.PP
+Any unmatched [ is a REG_EBRACK error.
+.PP
+Equivalence classes cannot begin or end bracket-expression ranges.
+The endpoint of one range cannot begin another.
+.PP
+RE_DUP_MAX, the limit on repetition counts in bounded repetitions, is 255.
+.PP
+A repetition operator (?, *, +, or bounds) cannot follow another
+repetition operator.
+A repetition operator cannot begin an expression or subexpression
+or follow `^' or `|'.
+.PP
+`|' cannot appear first or last in a (sub)expression or after another `|',
+i.e. an operand of `|' cannot be an empty subexpression.
+An empty parenthesized subexpression, `()', is legal and matches an
+empty (sub)string.
+An empty string is not a legal RE.
+.PP
+A `{' followed by a digit is considered the beginning of bounds for a
+bounded repetition, which must then follow the syntax for bounds.
+A `{' \fInot\fR followed by a digit is considered an ordinary character.
+.PP
+`^' and `$' beginning and ending subexpressions in obsolete (``basic'')
+REs are anchors, not ordinary characters.

+.SH HISTORY
+Written by Henry Spencer at University of Toronto,
+henry@zoo.toronto.edu.
+.SH BUGS
+This is an alpha release with known defects.
+Please report problems.
+.PP
+There is one known functionality bug.
+The implementation of internationalization is incomplete:
+the locale is always assumed to be the default one of 1003.2,
+and only the collating elements etc. of that locale are available.
+.PP
+The back-reference code is subtle and doubts linger about its correctness
+in complex cases.
+.PP
+.I Regexec
+performance is poor.
+This will improve with later releases.
+.I Nmatch
+exceeding 0 is expensive;
+.I nmatch
+exceeding 1 is worse.
+.I Regexec
+is largely insensitive to RE complexity \fIexcept\fR that back
+references are massively expensive.
+RE length does matter; in particular, there is a strong speed bonus
+for keeping RE length under about 30 characters,
+with most special characters counting roughly double.
+.PP
+.I Regcomp
+implements bounded repetitions by macro expansion,
+which is costly in time and space if counts are large
+or bounded repetitions are nested.
+An RE like, say,
+`((((a{1,100}){1,100}){1,100}){1,100}){1,100}'
+will (eventually) run almost any existing machine out of swap space.
+.PP
+There are suspected problems with response to obscure error conditions.
+Notably,
+certain kinds of internal overflow,
+produced only by truly enormous REs or by multiply nested bounded repetitions,
+are probably not handled well.
+.PP
+Due to a mistake in 1003.2, things like `a)b' are legal REs because `)' is
+a special character only in the presence of a previous unmatched `('.
+This can't be fixed until the spec is fixed.
+.PP
+The standard's definition of back references is vague.
+For example, does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?
+Until the standard is clarified,
+behavior in such cases should not be relied on.
+.PP
+The implementation of word-boundary matching is a bit of a kludge,
+and bugs may lurk in combinations of word-boundary matching and anchoring.

+.TH REGEX 7 "7 Feb 1994"
+.BY "Henry Spencer"
+.SH NAME
+regex \- POSIX 1003.2 regular expressions
+.SH DESCRIPTION
+Regular expressions (``RE''s),
+as defined in POSIX 1003.2, come in two forms:
+modern REs (roughly those of
+.IR egrep ;
+1003.2 calls these ``extended'' REs)
+and obsolete REs (roughly those of
+.IR ed ;
+1003.2 ``basic'' REs).
+Obsolete REs mostly exist for backward compatibility in some old programs;
+they will be discussed at the end.
+1003.2 leaves some aspects of RE syntax and semantics open;
+`\(dg' marks decisions on these aspects that
+may not be fully portable to other 1003.2 implementations.
+.PP
+A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR,
+separated by `|'.
+It matches anything that matches one of the branches.
+.PP
+A branch is one\(dg or more \fIpieces\fR, concatenated.
+It matches a match for the first, followed by a match for the second, etc.
+.PP
+A piece is an \fIatom\fR possibly followed
+by a single\(dg `*', `+', `?', or \fIbound\fR.
+An atom followed by `*' matches a sequence of 0 or more matches of the atom.
+An atom followed by `+' matches a sequence of 1 or more matches of the atom.
+An atom followed by `?' matches a sequence of 0 or 1 matches of the atom.
+.PP
+A \fIbound\fR is `{' followed by an unsigned decimal integer,
+possibly followed by `,'
+possibly followed by another unsigned decimal integer,
+always followed by `}'.
+The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive,
+and if there are two of them, the first may not exceed the second.
+An atom followed by a bound containing one integer \fIi\fR
+and no comma matches
+a sequence of exactly \fIi\fR matches of the atom.
+An atom followed by a bound
+containing one integer \fIi\fR and a comma matches
+a sequence of \fIi\fR or more matches of the atom.
+An atom followed by a bound
+containing two integers \fIi\fR and \fIj\fR matches
+a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom.
+.PP
+An atom is a regular expression enclosed in `()' (matching a match for the
+regular expression),
+an empty set of `()' (matching the null string)\(dg,
+a \fIbracket expression\fR (see below), `.'
+(matching any single character), `^' (matching the null string at the
+beginning of a line), `$' (matching the null string at the
+end of a line), a `\e' followed by one of the characters
+`^.[$()|*+?{\e'
+(matching that character taken as an ordinary character),
+a `\e' followed by any other character\(dg
+(matching that character taken as an ordinary character,
+as if the `\e' had not been present\(dg),
+or a single character with no other significance (matching that character).
+A `{' followed by a character other than a digit is an ordinary
+character, not the beginning of a bound\(dg.
+It is illegal to end an RE with `\e'.
+.PP
+A \fIbracket expression\fR is a list of characters enclosed in `[]'.
+It normally matches any single character from the list (but see below).
+If the list begins with `^',
+it matches any single character
+(but see below) \fInot\fR from the rest of the list.
+If two characters in the list are separated by `\-', this is shorthand
+for the full \fIrange\fR of characters between those two (inclusive) in the
+collating sequence,
+e.g. `[0-9]' in ASCII matches any decimal digit.
+It is illegal\(dg for two ranges to share an
+endpoint, e.g. `a-c-e'.
+Ranges are very collating-sequence-dependent,
+and portable programs should avoid relying on them.
+.PP
+To include a literal `]' in the list, make it the first character
+(following a possible `^').
+To include a literal `\-', make it the first or last character,
+or the second endpoint of a range.
+To use a literal `\-' as the first endpoint of a range,
+enclose it in `[.' and `.]' to make it a collating element (see below).
+With the exception of these and some combinations using `[' (see next
+paragraphs), all other special characters, including `\e', lose their
+special significance within a bracket expression.
+.PP
+Within a bracket expression, a collating element (a character,
+a multi-character sequence that collates as if it were a single character,
+or a collating-sequence name for either)
+enclosed in `[.' and `.]' stands for the
+sequence of characters of that collating element.
+The sequence is a single element of the bracket expression's list.
+A bracket expression containing a multi-character collating element 
+can thus match more than one character,
+e.g. if the collating sequence includes a `ch' collating element,
+then the RE `[[.ch.]]*c' matches the first five characters
+of `chchcc'.
+.PP
+Within a bracket expression, a collating element enclosed in `[=' and
+`=]' is an equivalence class, standing for the sequences of characters
+of all collating elements equivalent to that one, including itself.
+(If there are no other equivalent collating elements,
+the treatment is as if the enclosing delimiters were `[.' and `.]'.)
+For example, if o and \o'o^' are the members of an equivalence class,
+then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous.
+An equivalence class may not\(dg be an endpoint
+of a range.
+.PP
+Within a bracket expression, the name of a \fIcharacter class\fR enclosed
+in `[:' and `:]' stands for the list of all characters belonging to that
+class.
+Standard character class names are:
+.PP
+.RS
+.nf
+.ta 3c 6c 9c
+alnum	digit	punct
+alpha	graph	space
+blank	lower	upper
+cntrl	print	xdigit
+.fi
+.RE
+.PP
+These stand for the character classes defined in
+.IR ctype (3).
+A locale may provide others.
+A character class may not be used as an endpoint of a range.
+.PP
+There are two special cases\(dg of bracket expressions:
+the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at
+the beginning and end of a word respectively.
+A word is defined as a sequence of
+word characters
+which is neither preceded nor followed by
+word characters.
+A word character is an
+.I alnum
+character (as defined by
+.IR ctype (3))
+or an underscore.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+In the event that an RE could match more than one substring of a given
+string,
+the RE matches the one starting earliest in the string.
+If the RE could match more than one substring starting at that point,
+it matches the longest.
+Subexpressions also match the longest possible substrings, subject to
+the constraint that the whole match be as long as possible,
+with subexpressions starting earlier in the RE taking priority over
+ones starting later.
+Note that higher-level subexpressions thus take priority over
+their lower-level component subexpressions.
+.PP
+Match lengths are measured in characters, not collating elements.
+A null string is considered longer than no match at all.
+For example,
+`bb*' matches the three middle characters of `abbbc',
+`(wee|week)(knights|nights)' matches all ten characters of `weeknights',
+when `(.*).*' is matched against `abc' the parenthesized subexpression
+matches all three characters, and
+when `(a*)*' is matched against `bc' both the whole RE and the parenthesized
+subexpression match the null string.
+.PP
+If case-independent matching is specified,
+the effect is much as if all case distinctions had vanished from the
+alphabet.
+When an alphabetic that exists in multiple cases appears as an
+ordinary character outside a bracket expression, it is effectively
+transformed into a bracket expression containing both cases,
+e.g. `x' becomes `[xX]'.
+When it appears inside a bracket expression, all case counterparts
+of it are added to the bracket expression, so that (e.g.) `[x]'
+becomes `[xX]' and `[^x]' becomes `[^xX]'.
+.PP
+No particular limit is imposed on the length of REs\(dg.
+Programs intended to be portable should not employ REs longer
+than 256 bytes,
+as an implementation can refuse to accept such REs and remain
+POSIX-compliant.
+.PP
+Obsolete (``basic'') regular expressions differ in several respects.
+`|', `+', and `?' are ordinary characters and there is no equivalent
+for their functionality.
+The delimiters for bounds are `\e{' and `\e}',
+with `{' and `}' by themselves ordinary characters.
+The parentheses for nested subexpressions are `\e(' and `\e)',
+with `(' and `)' by themselves ordinary characters.
+`^' is an ordinary character except at the beginning of the
+RE or\(dg the beginning of a parenthesized subexpression,
+`$' is an ordinary character except at the end of the
+RE or\(dg the end of a parenthesized subexpression,
+and `*' is an ordinary character if it appears at the beginning of the
+RE or the beginning of a parenthesized subexpression
+(after a possible leading `^').
+Finally, there is one new type of atom, a \fIback reference\fR:
+`\e' followed by a non-zero decimal digit \fId\fR
+matches the same sequence of characters
+matched by the \fId\fRth parenthesized subexpression
+(numbering subexpressions by the positions of their opening parentheses,
+left to right),
+so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'.
+.SH SEE ALSO
+regex(3)
+.PP
+POSIX 1003.2, section 2.8 (Regular Expression Notation).
+.SH BUGS
+Having two kinds of REs is a botch.
+.PP
+The current 1003.2 spec says that `)' is an ordinary character in
+the absence of an unmatched `(';
+this was an unintentional result of a wording error,
+and change is likely.
+Avoid relying on it.
+.PP
+Back references are a dreadful botch,
+posing major problems for efficient implementations.
+They are also somewhat vaguely defined
+(does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?).
+Avoid using them.
+.PP
+1003.2's specification of case-independent matching is vague.
+The ``one case implies all cases'' definition given above
+is current consensus among implementors as to the right interpretation.
+.PP
+The syntax for word boundaries is incredibly ugly.

+/* alloca.c -- allocate automatically reclaimed memory
+   (Mostly) portable public-domain implementation -- D A Gwyn
+
+   This implementation of the PWB library alloca function,
+   which is used to allocate space off the run-time stack so
+   that it is automatically reclaimed upon procedure exit,
+   was inspired by discussions with J. Q. Johnson of Cornell.
+   J.Otto Tennant <jot@cray.com> contributed the Cray support.
+
+   There are some preprocessor constants that can
+   be defined when compiling for your specific system, for
+   improved efficiency; however, the defaults should be okay.
+
+   The general concept of this implementation is to keep
+   track of all alloca-allocated blocks, and reclaim any
+   that are found to be deeper in the stack than the current
+   invocation.  This heuristic does not reclaim storage as
+   soon as it becomes invalid, but it will do so eventually.
+
+   As a special case, alloca(0) reclaims storage without
+   allocating any.  It is a good idea to use alloca(0) in
+   your main control loop, etc. to force garbage collection.  */

+# Distribution generator for CVS based packages.
+# To work, this script needs a consistent tagging of all releases.
+# Each release of a package should have a tag of the form
+#
+#  <package>_<version>
+#
+# where <package> is the package name and the CVS module
+# and <version> s the version number with underscores instead of dots.
+#
+# For example: cvs tag php_3_0a1
+#
+# The distribution ends up in a .tar.gz file that contains the distribution
+# in a directory called <package>-<version>.  The distribution contains all
+# directories from the CVS module except the one called "nodist", but only
+# the files INSTALL, README and config* are included.
+#
+# Since you can no longer set the CVS password via an env variable, you
+# need to have previously done a cvs login for the server and user id
+# this script uses so it will have an entry in your ~/.cvspasswd file.

+[PHP_3]
+
+;;;;;;;;;;;;;;;;;;;
+; About this file ;
+;;;;;;;;;;;;;;;;;;;
+; This file controls many aspects of PHP's behavior.  In order for PHP to
+; read it, it must be named 'php3.ini'.  PHP looks for it in the current
+; working directory, in the path designated by the environment variable
+; PHPRC, and in the path that was defined in compile time (in that order).
+; Under Windows, the compile-time path is the Windows directory.  The
+; path in which the php3.ini file is looked for can be overriden using
+; the -c argument in command line mode.
+;
+; The syntax of the file is extremely simple.  Whitespace and Lines
+; beginning with a semicolon are silently ignored (as you probably guessed).
+; Section headers (e.g. [Foo]) are also silently ignored, even though
+; they might mean something in the future (they probably won't).
+;
+; Options are specified using the syntax key = value or key = "complex value".
+; Key names are *case sensitive*.  foo = bar is different from FOO = bar.
+; 'value' can be any number, word or keyword (keywords are On, Off, True,
+; False, Yes and No, and are case insensitive).
+; 'complex value' can be just about anything, expcept for " and a newline
+; Boolean flags can be turned on using the values 1, On, True or Yes.
+; They can be turned off using the values 0, Off, False or No.
+;
+; All the values in the php3.ini-dist file correspond to the builtin
+; defaults (that is, if no php3.ini is used, or if you delete these lines,
+; the builtin defaults will be identical).

+                        FOR IMMEDIATE RELEASE
+
+                           PHP 3.0 RELEASED
+
+June 6, 1998 -- The PHP Development Team announced the release of
+PHP 3.0, the latest release of the server-side scripting solution already
+in use on over 70,000 World Wide Web sites.
+
+This all-new version of the popular scripting language includes support
+for all major operating systems (Windows 95/NT, most versions of Unix,
+and Macintosh) and web servers (including Apache, Netscape servers,
+WebSite Pro, and Microsoft Internet Information Server).
+
+PHP 3.0 also supports a wide range of databases, including Oracle, Sybase,
+Solid, MySQ, mSQL, and PostgreSQL, as well as ODBC data sources.
+
+New features include persistent database connections, support for the
+SNMP and IMAP protocols, and a revamped C API for extending the language
+with new features.
+
+"PHP is a very programmer-friendly scripting language suitable for
+people with little or no programming experience as well as the
+seasoned web developer who needs to get things done quickly.  The
+best thing about PHP is that you get results quickly," said
+Rasmus Lerdorf, one of the developers of the language.
+
+"Version 3 provides a much more powerful, reliable and efficient
+implementation of the language, while maintaining the ease of use and 
+rapid development that were the key to PHP's success in the past", 
+added Andi Gutmans, one of the implementors of the new language core.
+
+"At Circle Net we have found PHP to be the most robust platform for
+rapid web-based application development available today," said Troy
+Cobb, Chief Technology Officer at Circle Net, Inc.  "Our use of PHP
+has cut our development time in half, and more than doubled our client
+satisfaction.  PHP has enabled us to provide database-driven dynamic
+solutions which perform at phenomenal speeds."
+
+PHP 3.0 is available for free download in source form and binaries for
+several platforms at http://www.php.net/.
+
+The PHP Development Team is an international group of programmers who
+lead the open development of PHP and related projects.
+
+For more information, the PHP Development Team can be contacted at
+core@php.net.

+Thu Mar 17 23:17:18 EST 1994

+
+See WHATSNEW for change listing.
+
+installation notes:
+--------
+Read the comments at the beginning of Makefile before running.
+
+Utils.h contains some things that just might have to be modified on
+some systems, as well as a nested include (ugh) of <assert.h>.
+
+The "fake" directory contains quick-and-dirty fakes for some header
+files and routines that old systems may not have.  Note also that
+-DUSEBCOPY will make utils.h substitute bcopy() for memmove().
+
+After that, "make r" will build regcomp.o, regexec.o, regfree.o,
+and regerror.o (the actual routines), bundle them together into a test
+program, and run regression tests on them.  No output is good output.
+
+"make lib" builds just the .o files for the actual routines (when
+you're happy with testing and have adjusted CFLAGS for production),
+and puts them together into libregex.a.  You can pick up either the
+library or *.o ("make lib" makes sure there are no other .o files left
+around to confuse things).
+
+Main.c, debug.c, split.c are used for regression testing but are not part
+of the RE routines themselves.
+
+Regex.h goes in /usr/include.  All other .h files are internal only.

+New in alpha3.4:  The complex bug alluded to below has been fixed (in a
+slightly kludgey temporary way that may hurt efficiency a bit; this is
+another "get it out the door for 4.4" release).  The tests at the end of
+the tests file have accordingly been uncommented.  The primary sign of
+the bug was that something like a?b matching ab matched b rather than ab.
+(The bug was essentially specific to this exact situation, else it would
+have shown up earlier.)
+
+New in alpha3.3:  The definition of word boundaries has been altered
+slightly, to more closely match the usual programming notion that "_"
+is an alphabetic.  Stuff used for pre-ANSI systems is now in a subdir,
+and the makefile no longer alludes to it in mysterious ways.  The
+makefile has generally been cleaned up some.  Fixes have been made
+(again!) so that the regression test will run without -DREDEBUG, at
+the cost of weaker checking.  A workaround for a bug in some folks'
+<assert.h> has been added.  And some more things have been added to
+tests, including a couple right at the end which are commented out
+because the code currently flunks them (complex bug; fix coming).
+Plus the usual minor cleanup.
+
+New in alpha3.2:  Assorted bits of cleanup and portability improvement
+(the development base is now a BSDI system using GCC instead of an ancient
+Sun system, and the newer compiler exposed some glitches).  Fix for a
+serious bug that affected REs using many [] (including REG_ICASE REs
+because of the way they are implemented), *sometimes*, depending on
+memory-allocation patterns.  The header-file prototypes no longer name
+the parameters, avoiding possible name conflicts.  The possibility that
+some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
+now handled gracefully.  "uchar" is no longer used as an internal type
+name (too many people have the same idea).  Still the same old lousy
+performance, alas.
+
+New in alpha3.1:  Basically nothing, this release is just a bookkeeping
+convenience.  Stay tuned.
+
+New in alpha3.0:  Performance is no better, alas, but some fixes have been
+made and some functionality has been added.  (This is basically the "get
+it out the door in time for 4.4" release.)  One bug fix:  regfree() didn't
+free the main internal structure (how embarrassing).  It is now possible
+to put NULs in either the RE or the target string, using (resp.) a new
+REG_PEND flag and the old REG_STARTEND flag.  The REG_NOSPEC flag to
+regcomp() makes all characters ordinary, so you can match a literal
+string easily (this will become more useful when performance improves!).
+There are now primitives to match beginnings and ends of words, although
+the syntax is disgusting and so is the implementation.  The REG_ATOI
+debugging interface has changed a bit.  And there has been considerable
+internal cleanup of various kinds.
+
+New in alpha2.3:  Split change list out of README, and moved flags notes
+into Makefile.  Macro-ized the name of regex(7) in regex(3), since it has
+to change for 4.4BSD.  Cleanup work in engine.c, and some new regression
+tests to catch tricky cases thereof.
+
+New in alpha2.2:  Out-of-date manpages updated.  Regerror() acquires two
+small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
+in my own test program and might be useful to others for similar purposes.
+The regression test will now compile (and run) without REDEBUG.  The
+BRE \$ bug is fixed.  Most uses of "uchar" are gone; it's all chars now.
+Char/uchar parameters are now written int/unsigned, to avoid possible
+portability problems with unpromoted parameters.  Some unsigned casts have
+been introduced to minimize portability problems with shifting into sign
+bits.
+
+New in alpha2.1:  Lots of little stuff, cleanup and fixes.  The one big
+thing is that regex.h is now generated, using mkh, rather than being
+supplied in the distribution; due to circularities in dependencies,
+you have to build regex.h explicitly by "make h".  The two known bugs
+have been fixed (and the regression test now checks for them), as has a
+problem with assertions not being suppressed in the absence of REDEBUG.
+No performance work yet.
+
+New in alpha2:  Backslash-anything is an ordinary character, not an
+error (except, of course, for the handful of backslashed metacharacters
+in BREs), which should reduce script breakage.  The regression test
+checks *where* null strings are supposed to match, and has generally
+been tightened up somewhat.  Small bug fixes in parameter passing (not
+harmful, but technically errors) and some other areas.  Debugging
+invoked by defining REDEBUG rather than not defining NDEBUG.
+
+New in alpha+3:  full prototyping for internal routines, using a little
+helper program, mkh, which extracts prototypes given in stylized comments.
+More minor cleanup.  Buglet fix:  it's CHAR_BIT, not CHAR_BITS.  Simple
+pre-screening of input when a literal string is known to be part of the
+RE; this does wonders for performance.
+
+New in alpha+2:  minor bits of cleanup.  Notably, the number "32" for the
+word width isn't hardwired into regexec.c any more, the public header
+file prototypes the functions if __STDC__ is defined, and some small typos
+in the manpages have been fixed.
+
+New in alpha+1:  improvements to the manual pages, and an important
+extension, the REG_STARTEND option to regexec().

+.SH DESCRIPTION
+These routines implement POSIX 1003.2 regular expressions (``RE''s);
+see
+.ZR .
+.I Regcomp
+compiles an RE written as a string into an internal form,
+.I regexec
+matches that internal form against a string and reports results,
+.I regerror
+transforms error codes from either into human-readable messages,
+and
+.I regfree
+frees any dynamically-allocated storage used by the internal form
+of an RE.
+.PP
+The header
+.I <regex.h>
+declares two structure types,
+.I regex_t
+and
+.IR regmatch_t ,
+the former for compiled internal forms and the latter for match reporting.
+It also declares the four functions,
+a type
+.IR regoff_t ,
+and a number of constants with names starting with ``REG_''.
+.PP
+.I Regcomp
+compiles the regular expression contained in the
+.I pattern
+string,
+subject to the flags in
+.IR cflags ,
+and places the results in the
+.I regex_t
+structure pointed to by
+.IR preg .
+.I Cflags
+is the bitwise OR of zero or more of the following flags:
+.IP REG_EXTENDED \w'REG_EXTENDED'u+2n
+Compile modern (``extended'') REs,
+rather than the obsolete (``basic'') REs that
+are the default.
+.IP REG_BASIC
+This is a synonym for 0,
+provided as a counterpart to REG_EXTENDED to improve readability.
+.IP REG_NOSPEC
+Compile with recognition of all special characters turned off.
+All characters are thus considered ordinary,
+so the ``RE'' is a literal string.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+REG_EXTENDED and REG_NOSPEC may not be used
+in the same call to
+.IR regcomp .
+.IP REG_ICASE
+Compile for matching that ignores upper/lower case distinctions.
+See
+.ZR .
+.IP REG_NOSUB
+Compile for matching that need only report success or failure,
+not what was matched.
+.IP REG_NEWLINE
+Compile for newline-sensitive matching.
+By default, newline is a completely ordinary character with no special
+meaning in either REs or strings.
+With this flag,
+`[^' bracket expressions and `.' never match newline,
+a `^' anchor matches the null string after any newline in the string
+in addition to its normal function,
+and the `$' anchor matches the null string before any newline in the
+string in addition to its normal function.
+.IP REG_PEND
+The regular expression ends,
+not at the first NUL,
+but just before the character pointed to by the
+.I re_endp
+member of the structure pointed to by
+.IR preg .
+The
+.I re_endp
+member is of type
+.IR const\ char\ * .
+This flag permits inclusion of NULs in the RE;
+they are considered ordinary characters.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+When successful,
+.I regcomp
+returns 0 and fills in the structure pointed to by
+.IR preg .
+One member of that structure
+(other than
+.IR re_endp )
+is publicized:
+.IR re_nsub ,
+of type
+.IR size_t ,
+contains the number of parenthesized subexpressions within the RE
+(except that the value of this member is undefined if the
+REG_NOSUB flag was used).
+If
+.I regcomp
+fails, it returns a non-zero error code;
+see DIAGNOSTICS.
+.PP
+.I Regexec
+matches the compiled RE pointed to by
+.I preg
+against the
+.IR string ,
+subject to the flags in
+.IR eflags ,
+and reports results using
+.IR nmatch ,
+.IR pmatch ,
+and the returned value.
+The RE must have been compiled by a previous invocation of
+.IR regcomp .
+The compiled form is not altered during execution of
+.IR regexec ,
+so a single compiled RE can be used simultaneously by multiple threads.
+.PP
+By default,
+the NUL-terminated string pointed to by
+.I string
+is considered to be the text of an entire line, minus any terminating
+newline.
+The
+.I eflags
+argument is the bitwise OR of zero or more of the following flags:
+.IP REG_NOTBOL \w'REG_STARTEND'u+2n
+The first character of
+the string
+is not the beginning of a line, so the `^' anchor should not match before it.
+This does not affect the behavior of newlines under REG_NEWLINE.
+.IP REG_NOTEOL
+The NUL terminating
+the string
+does not end a line, so the `$' anchor should not match before it.
+This does not affect the behavior of newlines under REG_NEWLINE.
+.IP REG_STARTEND
+The string is considered to start at
+\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_so\fR
+and to have a terminating NUL located at
+\fIstring\fR\ + \fIpmatch\fR[0].\fIrm_eo\fR
+(there need not actually be a NUL at that location),
+regardless of the value of
+.IR nmatch .
+See below for the definition of
+.IR pmatch
+and
+.IR nmatch .
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+Note that a non-zero \fIrm_so\fR does not imply REG_NOTBOL;
+REG_STARTEND affects only the location of the string,
+not how it is matched.
+.PP
+See
+.ZR
+for a discussion of what is matched in situations where an RE or a
+portion thereof could match any of several substrings of
+.IR string .
+.PP
+Normally,
+.I regexec
+returns 0 for success and the non-zero code REG_NOMATCH for failure.
+Other non-zero error codes may be returned in exceptional situations;
+see DIAGNOSTICS.
+.PP
+If REG_NOSUB was specified in the compilation of the RE,
+or if
+.I nmatch
+is 0,
+.I regexec
+ignores the
+.I pmatch
+argument (but see below for the case where REG_STARTEND is specified).
+Otherwise,
+.I pmatch
+points to an array of
+.I nmatch
+structures of type
+.IR regmatch_t .
+Such a structure has at least the members
+.I rm_so
+and
+.IR rm_eo ,
+both of type
+.I regoff_t
+(a signed arithmetic type at least as large as an
+.I off_t
+and a
+.IR ssize_t ),
+containing respectively the offset of the first character of a substring
+and the offset of the first character after the end of the substring.
+Offsets are measured from the beginning of the
+.I string
+argument given to
+.IR regexec .
+An empty substring is denoted by equal offsets,
+both indicating the character following the empty substring.
+.PP
+The 0th member of the
+.I pmatch
+array is filled in to indicate what substring of
+.I string
+was matched by the entire RE.
+Remaining members report what substring was matched by parenthesized
+subexpressions within the RE;
+member
+.I i
+reports subexpression
+.IR i ,
+with subexpressions counted (starting at 1) by the order of their opening
+parentheses in the RE, left to right.
+Unused entries in the array\(emcorresponding either to subexpressions that
+did not participate in the match at all, or to subexpressions that do not
+exist in the RE (that is, \fIi\fR\ > \fIpreg\fR\->\fIre_nsub\fR)\(emhave both
+.I rm_so
+and
+.I rm_eo
+set to \-1.
+If a subexpression participated in the match several times,
+the reported substring is the last one it matched.
+(Note, as an example in particular, that when the RE `(b*)+' matches `bbb',
+the parenthesized subexpression matches each of the three `b's and then
+an infinite number of empty strings following the last `b',
+so the reported substring is one of the empties.)
+.PP
+If REG_STARTEND is specified,
+.I pmatch
+must point to at least one
+.I regmatch_t
+(even if
+.I nmatch
+is 0 or REG_NOSUB was specified),
+to hold the input offsets for REG_STARTEND.
+Use for output is still entirely controlled by
+.IR nmatch ;
+if
+.I nmatch
+is 0 or REG_NOSUB was specified,
+the value of
+.IR pmatch [0]
+will not be changed by a successful
+.IR regexec .
+.PP
+.I Regerror
+maps a non-zero
+.I errcode
+from either
+.I regcomp
+or
+.I regexec
+to a human-readable, printable message.
+If
+.I preg
+is non-NULL,
+the error code should have arisen from use of
+the
+.I regex_t
+pointed to by
+.IR preg ,
+and if the error code came from
+.IR regcomp ,
+it should have been the result from the most recent
+.I regcomp
+using that
+.IR regex_t .
+.RI ( Regerror
+may be able to supply a more detailed message using information
+from the
+.IR regex_t .)
+.I Regerror
+places the NUL-terminated message into the buffer pointed to by
+.IR errbuf ,
+limiting the length (including the NUL) to at most
+.I errbuf_size
+bytes.
+If the whole message won't fit,
+as much of it as will fit before the terminating NUL is supplied.
+In any case,
+the returned value is the size of buffer needed to hold the whole
+message (including terminating NUL).
+If
+.I errbuf_size
+is 0,
+.I errbuf
+is ignored but the return value is still correct.
+.PP
+If the
+.I errcode
+given to
+.I regerror
+is first ORed with REG_ITOA,
+the ``message'' that results is the printable name of the error code,
+e.g. ``REG_NOMATCH'',
+rather than an explanation thereof.
+If
+.I errcode
+is REG_ATOI,
+then
+.I preg
+shall be non-NULL and the
+.I re_endp
+member of the structure it points to
+must point to the printable name of an error code;
+in this case, the result in
+.I errbuf
+is the decimal digits of
+the numeric value of the error code
+(0 if the name is not recognized).
+REG_ITOA and REG_ATOI are intended primarily as debugging facilities;
+they are extensions,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+Be warned also that they are considered experimental and changes are possible.
+.PP
+.I Regfree
+frees any dynamically-allocated storage associated with the compiled RE
+pointed to by
+.IR preg .
+The remaining
+.I regex_t
+is no longer a valid compiled RE
+and the effect of supplying it to
+.I regexec
+or
+.I regerror
+is undefined.
+.PP
+None of these functions references global variables except for tables
+of constants;
+all are safe for use from multiple threads if the arguments are safe.
+.SH IMPLEMENTATION CHOICES
+There are a number of decisions that 1003.2 leaves up to the implementor,
+either by explicitly saying ``undefined'' or by virtue of them being
+forbidden by the RE grammar.
+This implementation treats them as follows.
+.PP
+See
+.ZR
+for a discussion of the definition of case-independent matching.
+.PP
+There is no particular limit on the length of REs,
+except insofar as memory is limited.
+Memory usage is approximately linear in RE size, and largely insensitive
+to RE complexity, except for bounded repetitions.
+See BUGS for one short RE using them
+that will run almost any system out of memory.
+.PP
+A backslashed character other than one specifically given a magic meaning
+by 1003.2 (such magic meanings occur only in obsolete [``basic''] REs)
+is taken as an ordinary character.
+.PP
+Any unmatched [ is a REG_EBRACK error.
+.PP
+Equivalence classes cannot begin or end bracket-expression ranges.
+The endpoint of one range cannot begin another.
+.PP
+RE_DUP_MAX, the limit on repetition counts in bounded repetitions, is 255.
+.PP
+A repetition operator (?, *, +, or bounds) cannot follow another
+repetition operator.
+A repetition operator cannot begin an expression or subexpression
+or follow `^' or `|'.
+.PP
+`|' cannot appear first or last in a (sub)expression or after another `|',
+i.e. an operand of `|' cannot be an empty subexpression.
+An empty parenthesized subexpression, `()', is legal and matches an
+empty (sub)string.
+An empty string is not a legal RE.
+.PP
+A `{' followed by a digit is considered the beginning of bounds for a
+bounded repetition, which must then follow the syntax for bounds.
+A `{' \fInot\fR followed by a digit is considered an ordinary character.
+.PP
+`^' and `$' beginning and ending subexpressions in obsolete (``basic'')
+REs are anchors, not ordinary characters.

+.SH HISTORY
+Written by Henry Spencer at University of Toronto,
+henry@zoo.toronto.edu.
+.SH BUGS
+This is an alpha release with known defects.
+Please report problems.
+.PP
+There is one known functionality bug.
+The implementation of internationalization is incomplete:
+the locale is always assumed to be the default one of 1003.2,
+and only the collating elements etc. of that locale are available.
+.PP
+The back-reference code is subtle and doubts linger about its correctness
+in complex cases.
+.PP
+.I Regexec
+performance is poor.
+This will improve with later releases.
+.I Nmatch
+exceeding 0 is expensive;
+.I nmatch
+exceeding 1 is worse.
+.I Regexec
+is largely insensitive to RE complexity \fIexcept\fR that back
+references are massively expensive.
+RE length does matter; in particular, there is a strong speed bonus
+for keeping RE length under about 30 characters,
+with most special characters counting roughly double.
+.PP
+.I Regcomp
+implements bounded repetitions by macro expansion,
+which is costly in time and space if counts are large
+or bounded repetitions are nested.
+An RE like, say,
+`((((a{1,100}){1,100}){1,100}){1,100}){1,100}'
+will (eventually) run almost any existing machine out of swap space.
+.PP
+There are suspected problems with response to obscure error conditions.
+Notably,
+certain kinds of internal overflow,
+produced only by truly enormous REs or by multiply nested bounded repetitions,
+are probably not handled well.
+.PP
+Due to a mistake in 1003.2, things like `a)b' are legal REs because `)' is
+a special character only in the presence of a previous unmatched `('.
+This can't be fixed until the spec is fixed.
+.PP
+The standard's definition of back references is vague.
+For example, does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?
+Until the standard is clarified,
+behavior in such cases should not be relied on.
+.PP
+The implementation of word-boundary matching is a bit of a kludge,
+and bugs may lurk in combinations of word-boundary matching and anchoring.

+.TH REGEX 7 "7 Feb 1994"
+.BY "Henry Spencer"
+.SH NAME
+regex \- POSIX 1003.2 regular expressions
+.SH DESCRIPTION
+Regular expressions (``RE''s),
+as defined in POSIX 1003.2, come in two forms:
+modern REs (roughly those of
+.IR egrep ;
+1003.2 calls these ``extended'' REs)
+and obsolete REs (roughly those of
+.IR ed ;
+1003.2 ``basic'' REs).
+Obsolete REs mostly exist for backward compatibility in some old programs;
+they will be discussed at the end.
+1003.2 leaves some aspects of RE syntax and semantics open;
+`\(dg' marks decisions on these aspects that
+may not be fully portable to other 1003.2 implementations.
+.PP
+A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR,
+separated by `|'.
+It matches anything that matches one of the branches.
+.PP
+A branch is one\(dg or more \fIpieces\fR, concatenated.
+It matches a match for the first, followed by a match for the second, etc.
+.PP
+A piece is an \fIatom\fR possibly followed
+by a single\(dg `*', `+', `?', or \fIbound\fR.
+An atom followed by `*' matches a sequence of 0 or more matches of the atom.
+An atom followed by `+' matches a sequence of 1 or more matches of the atom.
+An atom followed by `?' matches a sequence of 0 or 1 matches of the atom.
+.PP
+A \fIbound\fR is `{' followed by an unsigned decimal integer,
+possibly followed by `,'
+possibly followed by another unsigned decimal integer,
+always followed by `}'.
+The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive,
+and if there are two of them, the first may not exceed the second.
+An atom followed by a bound containing one integer \fIi\fR
+and no comma matches
+a sequence of exactly \fIi\fR matches of the atom.
+An atom followed by a bound
+containing one integer \fIi\fR and a comma matches
+a sequence of \fIi\fR or more matches of the atom.
+An atom followed by a bound
+containing two integers \fIi\fR and \fIj\fR matches
+a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom.
+.PP
+An atom is a regular expression enclosed in `()' (matching a match for the
+regular expression),
+an empty set of `()' (matching the null string)\(dg,
+a \fIbracket expression\fR (see below), `.'
+(matching any single character), `^' (matching the null string at the
+beginning of a line), `$' (matching the null string at the
+end of a line), a `\e' followed by one of the characters
+`^.[$()|*+?{\e'
+(matching that character taken as an ordinary character),
+a `\e' followed by any other character\(dg
+(matching that character taken as an ordinary character,
+as if the `\e' had not been present\(dg),
+or a single character with no other significance (matching that character).
+A `{' followed by a character other than a digit is an ordinary
+character, not the beginning of a bound\(dg.
+It is illegal to end an RE with `\e'.
+.PP
+A \fIbracket expression\fR is a list of characters enclosed in `[]'.
+It normally matches any single character from the list (but see below).
+If the list begins with `^',
+it matches any single character
+(but see below) \fInot\fR from the rest of the list.
+If two characters in the list are separated by `\-', this is shorthand
+for the full \fIrange\fR of characters between those two (inclusive) in the
+collating sequence,
+e.g. `[0-9]' in ASCII matches any decimal digit.
+It is illegal\(dg for two ranges to share an
+endpoint, e.g. `a-c-e'.
+Ranges are very collating-sequence-dependent,
+and portable programs should avoid relying on them.
+.PP
+To include a literal `]' in the list, make it the first character
+(following a possible `^').
+To include a literal `\-', make it the first or last character,
+or the second endpoint of a range.
+To use a literal `\-' as the first endpoint of a range,
+enclose it in `[.' and `.]' to make it a collating element (see below).
+With the exception of these and some combinations using `[' (see next
+paragraphs), all other special characters, including `\e', lose their
+special significance within a bracket expression.
+.PP
+Within a bracket expression, a collating element (a character,
+a multi-character sequence that collates as if it were a single character,
+or a collating-sequence name for either)
+enclosed in `[.' and `.]' stands for the
+sequence of characters of that collating element.
+The sequence is a single element of the bracket expression's list.
+A bracket expression containing a multi-character collating element 
+can thus match more than one character,
+e.g. if the collating sequence includes a `ch' collating element,
+then the RE `[[.ch.]]*c' matches the first five characters
+of `chchcc'.
+.PP
+Within a bracket expression, a collating element enclosed in `[=' and
+`=]' is an equivalence class, standing for the sequences of characters
+of all collating elements equivalent to that one, including itself.
+(If there are no other equivalent collating elements,
+the treatment is as if the enclosing delimiters were `[.' and `.]'.)
+For example, if o and \o'o^' are the members of an equivalence class,
+then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous.
+An equivalence class may not\(dg be an endpoint
+of a range.
+.PP
+Within a bracket expression, the name of a \fIcharacter class\fR enclosed
+in `[:' and `:]' stands for the list of all characters belonging to that
+class.
+Standard character class names are:
+.PP
+.RS
+.nf

+.RE
+.PP
+These stand for the character classes defined in
+.IR ctype (3).
+A locale may provide others.
+A character class may not be used as an endpoint of a range.
+.PP
+There are two special cases\(dg of bracket expressions:
+the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at
+the beginning and end of a word respectively.
+A word is defined as a sequence of
+word characters
+which is neither preceded nor followed by
+word characters.
+A word character is an
+.I alnum
+character (as defined by
+.IR ctype (3))
+or an underscore.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+In the event that an RE could match more than one substring of a given
+string,
+the RE matches the one starting earliest in the string.
+If the RE could match more than one substring starting at that point,
+it matches the longest.
+Subexpressions also match the longest possible substrings, subject to
+the constraint that the whole match be as long as possible,
+with subexpressions starting earlier in the RE taking priority over
+ones starting later.
+Note that higher-level subexpressions thus take priority over
+their lower-level component subexpressions.
+.PP
+Match lengths are measured in characters, not collating elements.
+A null string is considered longer than no match at all.
+For example,
+`bb*' matches the three middle characters of `abbbc',
+`(wee|week)(knights|nights)' matches all ten characters of `weeknights',
+when `(.*).*' is matched against `abc' the parenthesized subexpression
+matches all three characters, and
+when `(a*)*' is matched against `bc' both the whole RE and the parenthesized
+subexpression match the null string.
+.PP
+If case-independent matching is specified,
+the effect is much as if all case distinctions had vanished from the
+alphabet.
+When an alphabetic that exists in multiple cases appears as an
+ordinary character outside a bracket expression, it is effectively
+transformed into a bracket expression containing both cases,
+e.g. `x' becomes `[xX]'.
+When it appears inside a bracket expression, all case counterparts
+of it are added to the bracket expression, so that (e.g.) `[x]'
+becomes `[xX]' and `[^x]' becomes `[^xX]'.
+.PP
+No particular limit is imposed on the length of REs\(dg.
+Programs intended to be portable should not employ REs longer
+than 256 bytes,
+as an implementation can refuse to accept such REs and remain
+POSIX-compliant.
+.PP
+Obsolete (``basic'') regular expressions differ in several respects.
+`|', `+', and `?' are ordinary characters and there is no equivalent
+for their functionality.
+The delimiters for bounds are `\e{' and `\e}',
+with `{' and `}' by themselves ordinary characters.
+The parentheses for nested subexpressions are `\e(' and `\e)',
+with `(' and `)' by themselves ordinary characters.
+`^' is an ordinary character except at the beginning of the
+RE or\(dg the beginning of a parenthesized subexpression,
+`$' is an ordinary character except at the end of the
+RE or\(dg the end of a parenthesized subexpression,
+and `*' is an ordinary character if it appears at the beginning of the
+RE or the beginning of a parenthesized subexpression
+(after a possible leading `^').
+Finally, there is one new type of atom, a \fIback reference\fR:
+`\e' followed by a non-zero decimal digit \fId\fR
+matches the same sequence of characters
+matched by the \fId\fRth parenthesized subexpression
+(numbering subexpressions by the positions of their opening parentheses,
+left to right),
+so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'.
+.SH SEE ALSO
+regex(3)
+.PP
+POSIX 1003.2, section 2.8 (Regular Expression Notation).
+.SH BUGS
+Having two kinds of REs is a botch.
+.PP
+The current 1003.2 spec says that `)' is an ordinary character in
+the absence of an unmatched `(';
+this was an unintentional result of a wording error,
+and change is likely.
+Avoid relying on it.
+.PP
+Back references are a dreadful botch,
+posing major problems for efficient implementations.
+They are also somewhat vaguely defined
+(does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?).
+Avoid using them.
+.PP
+1003.2's specification of case-independent matching is vague.
+The ``one case implies all cases'' definition given above
+is current consensus among implementors as to the right interpretation.
+.PP
+The syntax for word boundaries is incredibly ugly.

+ * fine points:
+ *
+ * - OPLUS_ and O_PLUS are *inside* the loop they create.
+ * - OQUEST_ and O_QUEST are *outside* the bypass they create.
+ * - OCH_ and O_CH are *outside* the multi-way branch they create, while
+ *   OOR1 and OOR2 are respectively the end and the beginning of one of
+ *   the branches.  Note that there is an implicit OOR2 following OCH_
+ *   and an implicit OOR1 preceding O_CH.
+ *
+ * In state representations, an operator's bit is on to signify a state
+ * immediately *preceding* "execution" of that operator.

+# regular expression test set
+# Lines are at least three fields, separated by one or more tabs.  "" stands
+# for an empty field.  First field is an RE.  Second field is flags.  If
+# C flag given, regcomp() is expected to fail, and the third field is the
+# error name (minus the leading REG_).
+#
+# Otherwise it is expected to succeed, and the third field is the string to
+# try matching it against.  If there is no fourth field, the match is
+# expected to fail.  If there is a fourth field, it is the substring that
+# the RE is expected to match.  If there is a fifth field, it is a comma-
+# separated list of what the subexpressions should match, with - indicating
+# no match for that one.  In both the fourth and fifth fields, a (sub)field
+# starting with @ indicates that the (sub)expression is expected to match
+# a null string followed by the stuff after the @; this provides a way to
+# test where null strings match.  The character `N' in REs and strings
+# is newline, `S' is space, `T' is tab, `Z' is NUL.
+#
+# The full list of flags:
+#	-	placeholder, does nothing
