Move version from lib/ to cpan/

Whilst there are still several differences between what's in core and what's
in the CPAN tarball, moving the files in core to their own directory with
the same layout as the CPAN distribution simplifies things.

Somewhat surprisingly, none of the toolchain modules C<use version;> so
there's no need to add to lib/buildcustomize.pl

+
+=head1 DESCRIPTION
+
+Version objects were added to Perl in 5.10.  This module implements version
+objects for older version of Perl and provides the version object API for all
+versions of Perl.  All previous releases before 0.74 are deprecated and should
+not be used due to incompatible API changes.  Version 0.77 introduces the new
+'parse' and 'declare' methods to standardize usage.  You are strongly urged to
+set 0.77 as a minimum in your code, e.g.
+
+  use version 0.77; # even for Perl v.5.10.0
+
+=head1 TYPES OF VERSION OBJECTS
+
+There are two different types of version objects, corresponding to the two
+different styles of versions in use:
+
+=over 2
+
+=item Decimal Versions
+
+The classic floating-point number $VERSION.  The advantage to this style is
+that you don't need to do anything special, just type a number into your
+source file.  Quoting is recommended, as it ensures that trailing zeroes
+("1.50") are preserved in any warnings or other output.
+
+=item Dotted Decimal Versions
+
+The more modern form of version assignment, with 3 (or potentially more)
+integers separated by decimal points (e.g. v1.2.3).  This is the form that
+Perl itself has used since 5.6.0 was released.  The leading 'v' is now
+strongly recommended for clarity, and will throw a warning in a future
+release if omitted.  A leading 'v' character is required to pass the
+L</is_strict()> test.
+
+=back
+
+=head1 DECLARING VERSIONS
+
+If you have a module that uses a decimal $VERSION (floating point), and you
+do not intend to ever change that, this module is not for you.  There is
+nothing that version.pm gains you over a simple $VERSION assignment:
+
+  our $VERSION = "1.02";
+
+Since Perl v5.10.0 includes the version.pm comparison logic anyways,
+you don't need to do anything at all.
+
+=head2 How to convert a module from decimal to dotted-decimal
+
+If you have used a decimal $VERSION in the past and wish to switch to a
+dotted-decimal $VERSION, then you need to make a one-time conversion to
+the new format.
+
+B<Important Note>: you must ensure that your new $VERSION is numerically
+greater than your current decimal $VERSION; this is not always obvious. First,
+convert your old decimal version (e.g. 1.02) to a normalized dotted-decimal
+form:
+
+  $ perl -Mversion -e 'print version->parse("1.02")->normal'
+  v1.20.0
+
+Then increment any of the dotted-decimal components (v1.20.1 or v1.21.0).
+
+=head2 How to C<declare()> a dotted-decimal version
+
+  use version; our $VERSION = version->declare("v1.2.3");
+
+The C<declare()> method always creates dotted-decimal version objects.  When
+used in a module, you B<must> put it on the same line as "use version" to
+ensure that $VERSION is read correctly by PAUSE and installer tools.  You
+should also add 'version' to the 'configure_requires' section of your
+module metadata file.  See instructions in L<ExtUtils::MakeMaker> or
+L<Module::Build> for details.
+
+B<Important Note>: Even if you pass in what looks like a decimal number
+("1.2"), a dotted-decimal will be created ("v1.200.0"). To avoid confusion
+or unintentional errors on older Perls, follow these guidelines:
+
+=over 2
+
+=item *
+
+Always use a dotted-decimal with (at least) three components
+
+=item *
+
+Always use a leading-v
+
+=item *
+
+Always quote the version
+
+=back
+
+If you really insist on using version.pm with an ordinary decimal version,
+use C<parse()> instead of declare.  See the L<PARSING AND COMPARING VERSIONS>
+for details.
+
+See also L<version::Internals> for more on version number conversion,
+quoting, calculated version numbers and declaring developer or "alpha" version
+numbers.
+
+=head1 PARSING AND COMPARING VERSIONS
+
+If you need to compare version numbers, but can't be sure whether they are
+expressed as numbers, strings, v-strings or version objects,  then you should
+use version.pm to parse them all into objects for comparison.
+
+=head2 How to C<parse()> a version
+
+The C<parse()> method takes in anything that might be a version and returns
+a corresponding version object, doing any necessary conversion along the way.
+
+=over 2
+
+=item *
+
+Dotted-decimal: bare v-strings (v1.2.3) and strings with more than one
+decimal point and a leading 'v' ("v1.2.3"); NOTE you can technically use a
+v-string or strings with a leading-v and only one decimal point (v1.2 or
+"v1.2"), but you will confuse both yourself and others.
+
+=item *
+
+Decimal: regular decimal numbers (literal or in a string)
+
+=back
+
+Some examples:
+
+  $variable   version->parse($variable)
+  ---------   -------------------------
+  1.23        v1.230.0
+  "1.23"      v1.230.0
+  v1.23       v1.23.0
+  "v1.23"     v1.23.0
+  "1.2.3"     v1.2.3
+  "v1.2.3"    v1.2.3
+
+See L<version::Internals> for more on version number conversion.
+
+=head2 How to check for a legal version string
+
+If you do not want to actually create a full blown version object, but
+would still like to verify that a given string meets the criteria to
+be parsed as a version, there are two helper functions that can be
+employed directly:
+
+=over 4
+
+=item C<is_lax()>
+
+The lax criteria corresponds to what is currently allowed by the
+version parser.  All of the following formats are acceptable
+for dotted-decimal formats strings:
+
+    v1.2
+    1.2345.6
+    v1.23_4
+    1.2345
+    1.2345_01
+
+=item C<is_strict()>
+
+If you want to limit yourself to a much more narrow definition of what
+a version string constitutes, C<is_strict()> is limited to version
+strings like the following list:
+
+    v1.234.5
+    2.3456
+
+=back
+
+See L<version::Internals> for details of the regular expressions
+that define the legal version string forms, as well as how to use
+those regular expressions in your own code if C<is_lax()> and
+C<is_strict()> are not sufficient for your needs.
+
+=head2 How to compare version objects
+
+Version objects overload the C<cmp> and C<< <=> >> operators.  Perl
+automatically generates all of the other comparison operators based on those
+two so all the normal logical comparisons will work.
+
+  if ( version->parse($v1) == version->parse($v2) ) {
+    # do stuff
+  }
+
+If a version object is compared against a non-version object, the non-object
+term will be converted to a version object using C<parse()>.  This may give
+surprising results:
+
+  $v1 = version->parse("v0.95.0");
+  $bool = $v1 < 0.96; # FALSE since 0.96 is v0.960.0
+
+Always comparing to a version object will help avoid surprises:
+
+  $bool = $v1 < version->parse("v0.96.0"); # TRUE
+
+Note that "alpha" version objects (where the version string contains
+a trailing underscore segment) compare as less than the equivalent
+version without an underscore:
+
+  $bool = version->parse("1.23_45") < version->parse("1.2345"); # TRUE
+
+See L<version::Internals> for more details on "alpha" versions.
+
+=head1 OBJECT METHODS
+
+=head2 is_alpha()
+
+True if and only if the version object was created with a underscore, e.g.
+
+  version->parse('1.002_03')->is_alpha;  # TRUE
+  version->declare('1.2.3_4')->is_alpha; # TRUE
+
+=head2 is_qv()
+
+True only if the version object is a dotted-decimal version, e.g.
+
+  version->parse('v1.2.0')->is_qv;       # TRUE
+  version->declare('v1.2')->is_qv;       # TRUE
+  qv('1.2')->is_qv;                      # TRUE
+  version->parse('1.2')->is_qv;          # FALSE
+
+=head2 normal()
+
+Returns a string with a standard 'normalized' dotted-decimal form with a
+leading-v and at least 3 components.
+
+ version->declare('v1.2')->normal;  # v1.2.0
+ version->parse('1.2')->normal;     # v1.200.0
+
+=head2 numify()
+
+Returns a value representing the object in a pure decimal form without
+trailing zeroes.
+
+ version->declare('v1.2')->numify;  # 1.002
+ version->parse('1.2')->numify;     # 1.2
+
+=head2 stringify()
+
+Returns a string that is as close to the original representation as possible.
+If the original representation was a numeric literal, it will be returned the
+way perl would normally represent it in a string.  This method is used whenever
+a version object is interpolated into a string.
+
+ version->declare('v1.2')->stringify;    # v1.2
+ version->parse('1.200')->stringify;     # 1.200
+ version->parse(1.02_30)->stringify;     # 1.023
+
+=head1 EXPORTED FUNCTIONS
+
+=head2 qv()
+
+This function is no longer recommended for use, but is maintained for
+compatibility with existing code.  If you do not want to have it exported
+to your namespace, use this form:
+
+  use version 0.77 ();
+
+=head2 is_lax()
+
+(Not exported by default)
+
+This function takes a scalar argument and returns a boolean value indicating
+whether the argument meets the "lax" rules for a version number.  Leading and
+trailing spaces are not allowed.
+
+=head2 is_strict()
+
+(Not exported by default)
+
+This function takes a scalar argument and returns a boolean value indicating
+whether the argument meets the "strict" rules for a version number.  Leading
+and trailing spaces are not allowed.

+=head1 NAME
+
+version::Internals - Perl extension for Version Objects
+
+=head1 DESCRIPTION
+
+Overloaded version objects for all modern versions of Perl.  This documents
+the internal data representation and underlying code for version.pm.  See
+F<version.pod> for daily usage.  This document is only useful for users
+interested in the gory details.
+
+=head1 WHAT IS A VERSION?
+
+For the purposes of this module, a version "number" is a sequence of
+positive integer values separated by one or more decimal points and
+optionally a single underscore.  This corresponds to what Perl itself
+uses for a version, as well as extending the "version as number" that
+is discussed in the various editions of the Camel book.
+
+There are actually two distinct kinds of version objects:
+
+=over 4
+
+=item Decimal Versions
+
+Any version which "looks like a number", see L<Decimal Versions>.  This
+also includes versions with a single decimal point and a single embedded
+underscore, see L<Alpha Versions>, even though these must be quoted
+to preserve the underscore formatting.
+
+=item Dotted-Decimal Versions
+
+Also referred to as "Dotted-Integer", these contains more than one decimal
+point and may have an optional embedded underscore, see L<Dotted-Decimal
+Versions>.  This is what is commonly used in most open source software as
+the "external" version (the one used as part of the tag or tarfile name).
+A leading 'v' character is now required and will warn if it missing.
+
+=back
+
+Both of these methods will produce similar version objects, in that
+the default stringification will yield the version L<Normal Form> only
+if required:
+
+  $v  = version->new(1.002);     # 1.002, but compares like 1.2.0
+  $v  = version->new(1.002003);  # 1.002003
+  $v2 = version->new("v1.2.3");  # v1.2.3
+
+In specific, version numbers initialized as L<Decimal Versions> will
+stringify as they were originally created (i.e. the same string that was
+passed to C<new()>.  Version numbers initialized as L<Dotted-Decimal Versions>
+will be stringified as L<Normal Form>.
+
+=head2 Decimal Versions
+
+These correspond to historical versions of Perl itself prior to 5.6.0,
+as well as all other modules which follow the Camel rules for the
+$VERSION scalar.  A Decimal version is initialized with what looks like
+a floating point number.  Leading zeros B<are> significant and trailing
+zeros are implied so that a minimum of three places is maintained
+between subversions.  What this means is that any subversion (digits
+to the right of the decimal place) that contains less than three digits
+will have trailing zeros added to make up the difference, but only for
+purposes of comparison with other version objects.  For example:
+
+                                   # Prints     Equivalent to
+  $v = version->new(      1.2);    # 1.2        v1.200.0
+  $v = version->new(     1.02);    # 1.02       v1.20.0
+  $v = version->new(    1.002);    # 1.002      v1.2.0
+  $v = version->new(   1.0023);    # 1.0023     v1.2.300
+  $v = version->new(  1.00203);    # 1.00203    v1.2.30
+  $v = version->new( 1.002003);    # 1.002003   v1.2.3
+
+All of the preceding examples are true whether or not the input value is
+quoted.  The important feature is that the input value contains only a
+single decimal.  See also L<Alpha Versions>.
+
+IMPORTANT NOTE: As shown above, if your Decimal version contains more
+than 3 significant digits after the decimal place, it will be split on
+each multiple of 3, so 1.0003 is equivalent to v1.0.300, due to the need
+to remain compatible with Perl's own 5.005_03 == 5.5.30 interpretation.
+Any trailing zeros are ignored for mathematical comparison purposes.
+
+=head2 Dotted-Decimal Versions
+
+These are the newest form of versions, and correspond to Perl's own
+version style beginning with 5.6.0.  Starting with Perl 5.10.0,
+and most likely Perl 6, this is likely to be the preferred form.  This
+method normally requires that the input parameter be quoted, although
+Perl's after 5.8.1 can use v-strings as a special form of quoting, but
+this is highly discouraged.
+
+Unlike L<Decimal Versions>, Dotted-Decimal Versions have more than
+a single decimal point, e.g.:
+
+                                   # Prints
+  $v = version->new( "v1.200");    # v1.200.0
+  $v = version->new("v1.20.0");    # v1.20.0
+  $v = qv("v1.2.3");               # v1.2.3
+  $v = qv("1.2.3");                # v1.2.3
+  $v = qv("1.20");                 # v1.20.0
+
+In general, Dotted-Decimal Versions permit the greatest amount of freedom
+to specify a version, whereas Decimal Versions enforce a certain
+uniformity.  
+
+Just like L</Decimal Versions>, Dotted-Decimal Versions can be used as
+L</Alpha Versions>.
+
+=head2 Alpha Versions
+
+For module authors using CPAN, the convention has been to note unstable
+releases with an underscore in the version string. (See L<CPAN>.)  version.pm
+follows this convention and alpha releases will test as being newer than the
+more recent stable release, and less than the next stable release.  Only the
+last element may be separated by an underscore:
+
+  # Declaring
+  use version 0.77; our $VERSION = version->declare("v1.2_3");
+
+  # Parsing
+  $v1 = version->parse("v1.2_3");
+  $v1 = version->parse("1.002_003");
+
+Note that you B<must> quote the version when writing an alpha Decimal version.
+The stringified form of Decimal versions will always be the same string that
+was used to initialize the version object.
+
+=head2 Regular Expressions for Version Parsing
+
+A formalized definition of the legal forms for version strings is
+included in the main F<version.pm> file.  Primitives are included for
+common elements, although they are scoped to the file so they are useful
+for reference purposes only.  There are two publicly accessible scalars
+that can be used in other code (not exported):
+
+=over 4
+
+=item C<$version::LAX>
+
+This regexp covers all of the legal forms allowed under the current
+version string parser.  This is not to say that all of these forms
+are recommended, and some of them can only be used when quoted.
+
+For dotted decimals:
+
+    v1.2
+    1.2345.6
+    v1.23_4
+
+The leading 'v' is optional if two or more decimals appear.  If only
+a single decimal is included, then the leading 'v' is required to
+trigger the dotted-decimal parsing.  A leading zero is permitted,
+though not recommended except when quoted, because of the risk that
+Perl will treat the number as octal.  A trailing underscore plus one
+or more digits denotes an alpha or development release (and must be
+quoted to be parsed properly).
+
+For decimal versions:
+
+    1
+    1.2345
+    1.2345_01
+
+an integer portion, an optional decimal point, and optionally one or
+more digits to the right of the decimal are all required.  A trailing
+underscore is permitted and a leading zero is permitted.  Just like
+the lax dotted-decimal version, quoting the values is required for
+alpha/development forms to be parsed correctly.
+
+=item C<$version::STRICT>
+
+This regexp covers a much more limited set of formats and constitutes
+the best practices for initializing version objects.  Whether you choose
+to employ decimal or dotted-decimal for is a personal preference however.
+
+=over 4
+
+=item v1.234.5
+
+For dotted-decimal versions, a leading 'v' is required, with three or
+more sub-versions of no more than three digits.  A leading 0 (zero)
+before the first sub-version (in the above example, '1') is also
+prohibited.
+
+=item 2.3456
+
+For decimal versions, an integer portion (no leading 0), a decimal point,
+and one or more digits to the right of the decimal are all required.
+
+=back
+
+=back
+
+Both of the provided scalars are already compiled as regular expressions
+and do not contain either anchors or implicit groupings, so they can be
+included in your own regular expressions freely.  For example, consider
+the following code:
+
+	($pkg, $ver) =~ /
+		^[ \t]*
+		use [ \t]+($PKGNAME)
+		(?:[ \t]+($version::STRICT))?
+		[ \t]*;
+	/x;
+
+This would match a line of the form:
+
+	use Foo::Bar::Baz v1.2.3;	# legal only in Perl 5.8.1+
+
+where C<$PKGNAME> is another regular expression that defines the legal
+forms for package names.
+
+=head1 IMPLEMENTATION DETAILS
+
+=head2 Equivalence between Decimal and Dotted-Decimal Versions
+
+When Perl 5.6.0 was released, the decision was made to provide a
+transformation between the old-style decimal versions and new-style
+dotted-decimal versions:
+
+  5.6.0    == 5.006000
+  5.005_04 == 5.5.40
+
+The floating point number is taken and split first on the single decimal
+place, then each group of three digits to the right of the decimal makes up
+the next digit, and so on until the number of significant digits is exhausted,
+B<plus> enough trailing zeros to reach the next multiple of three.
+
+This was the method that version.pm adopted as well.  Some examples may be
+helpful:
+
+                            equivalent
+  decimal    zero-padded    dotted-decimal
+  -------    -----------    --------------
+  1.2        1.200          v1.200.0
+  1.02       1.020          v1.20.0
+  1.002      1.002          v1.2.0
+  1.0023     1.002300       v1.2.300
+  1.00203    1.002030       v1.2.30
+  1.002003   1.002003       v1.2.3
+
+=head2 Quoting Rules
+
+Because of the nature of the Perl parsing and tokenizing routines,
+certain initialization values B<must> be quoted in order to correctly
+parse as the intended version, especially when using the C<declare> or
+L</qv()> methods.  While you do not have to quote decimal numbers when
+creating version objects, it is always safe to quote B<all> initial values
+when using version.pm methods, as this will ensure that what you type is
+what is used.
+
+Additionally, if you quote your initializer, then the quoted value that goes
+B<in> will be exactly what comes B<out> when your $VERSION is printed
+(stringified).  If you do not quote your value, Perl's normal numeric handling
+comes into play and you may not get back what you were expecting.
+
+If you use a mathematic formula that resolves to a floating point number,
+you are dependent on Perl's conversion routines to yield the version you
+expect.  You are pretty safe by dividing by a power of 10, for example,
+but other operations are not likely to be what you intend.  For example:
+
+  $VERSION = version->new((qw$Revision: 1.4)[1]/10);
+  print $VERSION;          # yields 0.14
+  $V2 = version->new(100/9); # Integer overflow in decimal number
+  print $V2;               # yields something like 11.111.111.100
+
+Perl 5.8.1 and beyond are able to automatically quote v-strings but
+that is not possible in earlier versions of Perl.  In other words:
+
+  $version = version->new("v2.5.4");  # legal in all versions of Perl
+  $newvers = version->new(v2.5.4);    # legal only in Perl >= 5.8.1
+
+=head2 What about v-strings?
+
+There are two ways to enter v-strings: a bare number with two or more
+decimal points, or a bare number with one or more decimal points and a
+leading 'v' character (also bare).  For example:
+
+  $vs1 = 1.2.3; # encoded as \1\2\3
+  $vs2 = v1.2;  # encoded as \1\2
+
+However, the use of bare v-strings to initialize version objects is
+B<strongly> discouraged in all circumstances.  Also, bare
+v-strings are not completely supported in any version of Perl prior to
+5.8.1.
+
+If you insist on using bare v-strings with Perl > 5.6.0, be aware of the
+following limitations:
+
+1) For Perl releases 5.6.0 through 5.8.0, the v-string code merely guesses,
+based on some characteristics of v-strings.  You B<must> use a three part
+version, e.g. 1.2.3 or v1.2.3 in order for this heuristic to be successful.
+
+2) For Perl releases 5.8.1 and later, v-strings have changed in the Perl
+core to be magical, which means that the version.pm code can automatically
+determine whether the v-string encoding was used.
+
+3) In all cases, a version created using v-strings will have a stringified
+form that has a leading 'v' character, for the simple reason that sometimes
+it is impossible to tell whether one was present initially.
+
+=head2 Version Object Internals
+
+version.pm provides an overloaded version object that is designed to both
+encapsulate the author's intended $VERSION assignment as well as make it
+completely natural to use those objects as if they were numbers (e.g. for
+comparisons).  To do this, a version object contains both the original
+representation as typed by the author, as well as a parsed representation
+to ease comparisons.  Version objects employ L<overload> methods to
+simplify code that needs to compare, print, etc the objects.
+
+The internal structure of version objects is a blessed hash with several
+components:
+
+    bless( {
+      'original' => 'v1.2.3_4',
+      'alpha' => 1,
+      'qv' => 1,
+      'version' => [
+	1,
+	2,
+	3,
+	4
+      ]
+    }, 'version' );
+
+=over 4
+
+=item original
+
+A faithful representation of the value used to initialize this version
+object.  The only time this will not be precisely the same characters
+that exist in the source file is if a short dotted-decimal version like
+v1.2 was used (in which case it will contain 'v1.2').  This form is
+B<STRONGLY> discouraged, in that it will confuse you and your users.
+
+=item qv
+
+A boolean that denotes whether this is a decimal or dotted-decimal version.
+See L<version/is_qv()>.
+
+=item alpha
+
+A boolean that denotes whether this is an alpha version.  NOTE: that the
+underscore can only appear in the last position.  See L<version/is_alpha()>.
+
+=item version
+
+An array of non-negative integers that is used for comparison purposes with
+other version objects.
+
+=back
+
+=head2 Replacement UNIVERSAL::VERSION
+
+In addition to the version objects, this modules also replaces the core
+UNIVERSAL::VERSION function with one that uses version objects for its
+comparisons.  The return from this operator is always the stringified form
+as a simple scalar (i.e. not an object), but the warning message generated
+includes either the stringified form or the normal form, depending on how
+it was called.
+
+For example:
+
+  package Foo;
+  $VERSION = 1.2;
+
+  package Bar;
+  $VERSION = "v1.3.5"; # works with all Perl's (since it is quoted)
+
+  package main;
+  use version;
+
+  print $Foo::VERSION; # prints 1.2
+
+  print $Bar::VERSION; # prints 1.003005
+
+  eval "use foo 10";
+  print $@; # prints "foo version 10 required..."
+  eval "use foo 1.3.5; # work in Perl 5.6.1 or better
+  print $@; # prints "foo version 1.3.5 required..."
+
+  eval "use bar 1.3.6";
+  print $@; # prints "bar version 1.3.6 required..."
+  eval "use bar 1.004"; # note Decimal version
+  print $@; # prints "bar version 1.004 required..."
+
+
+IMPORTANT NOTE: This may mean that code which searches for a specific
+string (to determine whether a given module is available) may need to be
+changed.  It is always better to use the built-in comparison implicit in
+C<use> or C<require>, rather than manually poking at C<< class->VERSION >>
+and then doing a comparison yourself.
+
+The replacement UNIVERSAL::VERSION, when used as a function, like this:
+
+  print $module->VERSION;
+
+will also exclusively return the stringified form.  See L</Stringification>
+for more details.
+
+=head1 USAGE DETAILS
+
+=head2 Using modules that use version.pm
+
+As much as possible, the version.pm module remains compatible with all
+current code.  However, if your module is using a module that has defined
+C<$VERSION> using the version class, there are a couple of things to be
+aware of.  For purposes of discussion, we will assume that we have the
+following module installed:
+
+  package Example;
+  use version;  $VERSION = qv('1.2.2');
+  ...module code here...
+  1;
+
+=over 4
+
+=item Decimal versions always work
+
+Code of the form:
+
+  use Example 1.002003;
+
+will always work correctly.  The C<use> will perform an automatic
+C<$VERSION> comparison using the floating point number given as the first
+term after the module name (e.g. above 1.002.003).  In this case, the
+installed module is too old for the requested line, so you would see an
+error like:
+
+  Example version 1.002003 (v1.2.3) required--this is only version 1.002002 (v1.2.2)...
+
+=item Dotted-Decimal version work sometimes
+
+With Perl >= 5.6.2, you can also use a line like this:
+
+  use Example 1.2.3;
+
+and it will again work (i.e. give the error message as above), even with
+releases of Perl which do not normally support v-strings (see L<What about v-strings?> above).  This has to do with that fact that C<use> only checks
+to see if the second term I<looks like a number> and passes that to the
+replacement L<UNIVERSAL::VERSION|UNIVERSAL/VERSION>.  This is not true in Perl 5.005_04,
+however, so you are B<strongly encouraged> to always use a Decimal version
+in your code, even for those versions of Perl which support the Dotted-Decimal
+version.
+
+=back
+
+=head2 Object Methods
+
+=over 4
+
+=item new()
+
+Like many OO interfaces, the new() method is used to initialize version
+objects.  If two arguments are passed to C<new()>, the B<second> one will be
+used as if it were prefixed with "v".  This is to support historical use of the
+C<qw> operator with the CVS variable $Revision, which is automatically
+incremented by CVS every time the file is committed to the repository.
+
+In order to facilitate this feature, the following
+code can be employed:
+
+  $VERSION = version->new(qw$Revision: 2.7 $);
+
+and the version object will be created as if the following code
+were used:
+
+  $VERSION = version->new("v2.7");
+
+In other words, the version will be automatically parsed out of the
+string, and it will be quoted to preserve the meaning CVS normally
+carries for versions.  The CVS $Revision$ increments differently from
+Decimal versions (i.e. 1.10 follows 1.9), so it must be handled as if
+it were a Dotted-Decimal Version.
+
+A new version object can be created as a copy of an existing version
+object, either as a class method:
+
+  $v1 = version->new(12.3);
+  $v2 = version->new($v1);
+
+or as an object method:
+
+  $v1 = version->new(12.3);
+  $v2 = $v1->new(12.3);
+
+and in each case, $v1 and $v2 will be identical.  NOTE: if you create
+a new object using an existing object like this:
+
+  $v2 = $v1->new();
+
+the new object B<will not> be a clone of the existing object.  In the
+example case, $v2 will be an empty object of the same type as $v1.
+
+=back
+
+=over 4
+
+=item qv()
+
+An alternate way to create a new version object is through the exported
+qv() sub.  This is not strictly like other q? operators (like qq, qw),
+in that the only delimiters supported are parentheses (or spaces).  It is
+the best way to initialize a short version without triggering the floating
+point interpretation.  For example:
+
+  $v1 = qv(1.2);         # v1.2.0
+  $v2 = qv("1.2");       # also v1.2.0
+
+As you can see, either a bare number or a quoted string can usually
+be used interchangeably, except in the case of a trailing zero, which
+must be quoted to be converted properly.  For this reason, it is strongly
+recommended that all initializers to qv() be quoted strings instead of
+bare numbers.
+
+To prevent the C<qv()> function from being exported to the caller's namespace,
+either use version with a null parameter:
+
+  use version ();
+
+or just require version, like this:
+
+  require version;
+
+Both methods will prevent the import() method from firing and exporting the
+C<qv()> sub.
+
+=back
+
+For the subsequent examples, the following three objects will be used:
+
+  $ver   = version->new("1.2.3.4"); # see "Quoting Rules"
+  $alpha = version->new("1.2.3_4"); # see "Alpha Versions"
+  $nver  = version->new(1.002);     # see "Decimal Versions"
+
+=over 4
+
+=item Normal Form
+
+For any version object which is initialized with multiple decimal
+places (either quoted or if possible v-string), or initialized using
+the L<qv()|version/qv()> operator, the stringified representation is returned in
+a normalized or reduced form (no extraneous zeros), and with a leading 'v':
+
+  print $ver->normal;         # prints as v1.2.3.4
+  print $ver->stringify;      # ditto
+  print $ver;                 # ditto
+  print $nver->normal;        # prints as v1.2.0
+  print $nver->stringify;     # prints as 1.002,
+                              # see "Stringification"
+
+In order to preserve the meaning of the processed version, the
+normalized representation will always contain at least three sub terms.
+In other words, the following is guaranteed to always be true:
+
+  my $newver = version->new($ver->stringify);
+  if ($newver eq $ver ) # always true
+    {...}
+
+=back
+
+=over 4
+
+=item Numification
+
+Although all mathematical operations on version objects are forbidden
+by default, it is possible to retrieve a number which corresponds
+to the version object through the use of the $obj->numify
+method.  For formatting purposes, when displaying a number which
+corresponds a version object, all sub versions are assumed to have
+three decimal places.  So for example:
+
+  print $ver->numify;         # prints 1.002003004
+  print $nver->numify;        # prints 1.002
+
+Unlike the stringification operator, there is never any need to append
+trailing zeros to preserve the correct version value.
+
+=back
+
+=over 4
+
+=item Stringification
+
+The default stringification for version objects returns exactly the same
+string as was used to create it, whether you used C<new()> or C<qv()>,
+with one exception.  The sole exception is if the object was created using
+C<qv()> and the initializer did not have two decimal places or a leading
+'v' (both optional), then the stringified form will have a leading 'v'
+prepended, in order to support round-trip processing.
+
+For example:
+
+  Initialized as          Stringifies to
+  ==============          ==============
+  version->new("1.2")       1.2
+  version->new("v1.2")     v1.2
+  qv("1.2.3")               1.2.3
+  qv("v1.3.5")             v1.3.5
+  qv("1.2")                v1.2   ### exceptional case
+
+See also L<UNIVERSAL::VERSION|UNIVERSAL/VERSION>, as this also returns the stringified form
+when used as a class method.
+
+IMPORTANT NOTE: There is one exceptional cases shown in the above table
+where the "initializer" is not stringwise equivalent to the stringified
+representation.  If you use the C<qv>() operator on a version without a
+leading 'v' B<and> with only a single decimal place, the stringified output
+will have a leading 'v', to preserve the sense.  See the L</qv()> operator
+for more details.
+
+IMPORTANT NOTE 2: Attempting to bypass the normal stringification rules by
+manually applying L<numify()|version/numify()> and L<normal()|version/normal()>  will sometimes yield
+surprising results:
+
+  print version->new(version->new("v1.0")->numify)->normal; # v1.0.0
+
+The reason for this is that the L<numify()|version/numify()> operator will turn "v1.0"
+into the equivalent string "1.000000".  Forcing the outer version object
+to L<normal()|version/normal()> form will display the mathematically equivalent "v1.0.0".
+
+As the example in L</new()> shows, you can always create a copy of an
+existing version object with the same value by the very compact:
+
+  $v2 = $v1->new($v1);
+
+and be assured that both C<$v1> and C<$v2> will be completely equivalent,
+down to the same internal representation as well as stringification.
+
+=back
+
+=over 4
+
+=item Comparison operators
+
+Both C<cmp> and C<E<lt>=E<gt>> operators perform the same comparison between
+terms (upgrading to a version object automatically).  Perl automatically
+generates all of the other comparison operators based on those two.
+In addition to the obvious equalities listed below, appending a single
+trailing 0 term does not change the value of a version for comparison
+purposes.  In other words "v1.2" and "1.2.0" will compare as identical.
+
+For example, the following relations hold:
+
+  As Number        As String           Truth Value
+  -------------    ----------------    -----------
+  $ver >  1.0      $ver gt "1.0"       true
+  $ver <  2.5      $ver lt             true
+  $ver != 1.3      $ver ne "1.3"       true
+  $ver == 1.2      $ver eq "1.2"       false
+  $ver == 1.2.3.4  $ver eq "1.2.3.4"   see discussion below
+
+It is probably best to chose either the Decimal notation or the string
+notation and stick with it, to reduce confusion.  Perl6 version objects
+B<may> only support Decimal comparisons.  See also L<Quoting Rules>.
+
+WARNING: Comparing version with unequal numbers of decimal points (whether
+explicitly or implicitly initialized), may yield unexpected results at
+first glance.  For example, the following inequalities hold:
+
+  version->new(0.96)     > version->new(0.95); # 0.960.0 > 0.950.0
+  version->new("0.96.1") < version->new(0.95); # 0.096.1 < 0.950.0
+
+For this reason, it is best to use either exclusively L<Decimal Versions> or
+L<Dotted-Decimal Versions> with multiple decimal points.
+
+=back
+
+=over 4
+
+=item Logical Operators
+
+If you need to test whether a version object
+has been initialized, you can simply test it directly:
+
+  $vobj = version->new($something);
+  if ( $vobj )   # true only if $something was non-blank
+
+You can also test whether a version object is an alpha version, for
+example to prevent the use of some feature not present in the main
+release:
+
+  $vobj = version->new("1.2_3"); # MUST QUOTE
+  ...later...
+  if ( $vobj->is_alpha )       # True
