-=head1 NAME
-
-Pod::Checker, podchecker() - check pod documents for syntax errors
-
-=head1 SYNOPSIS
-
-  use Pod::Checker;
-
-  $syntax_okay = podchecker($filepath, $outputpath, %options);
-
-  my $checker = new Pod::Checker %options;
-  $checker->parse_from_file($filepath, \*STDERR);
-
-=head1 OPTIONS/ARGUMENTS
-
-C<$filepath> is the input POD to read and C<$outputpath> is
-where to write POD syntax error messages. Either argument may be a scalar
-indicating a file-path, or else a reference to an open filehandle.
-If unspecified, the input-file it defaults to C<\*STDIN>, and
-the output-file defaults to C<\*STDERR>.
-
-=head2 podchecker()
-
-This function can take a hash of options:
-
-=over 4
-
-=item B<-warnings> =E<gt> I<val>
-
-Turn warnings on/off. I<val> is usually 1 for on, but higher values
-trigger additional warnings. See L<"Warnings">.
-
-=back
-
-=head1 DESCRIPTION
-
-B<podchecker> will perform syntax checking of Perl5 POD format documentation.
-
-Curious/ambitious users are welcome to propose additional features they wish
-to see in B<Pod::Checker> and B<podchecker> and verify that the checks are
-consistent with L<perlpod>.
-
-The following checks are currently performed:
-
-=over 4
-
-=item *
-
-Unknown '=xxxx' commands, unknown 'XE<lt>...E<gt>' interior-sequences,
-and unterminated interior sequences.
-
-=item *
-
-Check for proper balancing of C<=begin> and C<=end>. The contents of such
-a block are generally ignored, i.e. no syntax checks are performed.
-
-=item *
-
-Check for proper nesting and balancing of C<=over>, C<=item> and C<=back>.
-
-=item *
-
-Check for same nested interior-sequences (e.g.
-C<LE<lt>...LE<lt>...E<gt>...E<gt>>).
-
-=item *
-
-Check for malformed or non-existing entities C<EE<lt>...E<gt>>.
-
-=item *
-
-Check for correct syntax of hyperlinks C<LE<lt>...E<gt>>. See L<perlpod>
-for details.
-
-=item *
-
-Check for unresolved document-internal links. This check may also reveal
-misspelled links that seem to be internal links but should be links
-to something else.
-
-=back
-
-=head1 DIAGNOSTICS
-
-=head2 Errors
-
-=over 4
-
-=item * empty =headn
-
-A heading (C<=head1> or C<=head2>) without any text? That ain't no
-heading!
-
-=item * =over on line I<N> without closing =back
-
-The C<=over> command does not have a corresponding C<=back> before the
-next heading (C<=head1> or C<=head2>) or the end of the file.
-
-=item * =item without previous =over
-
-=item * =back without previous =over
-
-An C<=item> or C<=back> command has been found outside a
-C<=over>/C<=back> block.
-
-=item * No argument for =begin
-
-A C<=begin> command was found that is not followed by the formatter
-specification.
-
-=item * =end without =begin
-
-A standalone C<=end> command was found.
-
-=item * Nested =begin's
-
-There were at least two consecutive C<=begin> commands without
-the corresponding C<=end>. Only one C<=begin> may be active at
-a time.
-
-=item * =for without formatter specification
-
-There is no specification of the formatter after the C<=for> command.
-
-=item * unresolved internal link I<NAME>
-
-The given link to I<NAME> does not have a matching node in the current
-POD. This also happened when a single word node name is not enclosed in
-C<"">.
-
-=item * Unknown command "I<CMD>"
-
-An invalid POD command has been found. Valid are C<=head1>, C<=head2>,
-C<=head3>, C<=head4>, C<=over>, C<=item>, C<=back>, C<=begin>, C<=end>,
-C<=for>, C<=pod>, C<=cut>
-
-=item * Unknown interior-sequence "I<SEQ>"
-
-An invalid markup command has been encountered. Valid are:
-C<BE<lt>E<gt>>, C<CE<lt>E<gt>>, C<EE<lt>E<gt>>, C<FE<lt>E<gt>>,
-C<IE<lt>E<gt>>, C<LE<lt>E<gt>>, C<SE<lt>E<gt>>, C<XE<lt>E<gt>>,
-C<ZE<lt>E<gt>>
-
-=item * nested commands I<CMD>E<lt>...I<CMD>E<lt>...E<gt>...E<gt>
-
-Two nested identical markup commands have been found. Generally this
-does not make sense.
-
-=item * garbled entity I<STRING>
-
-The I<STRING> found cannot be interpreted as a character entity.
-
-=item * Entity number out of range
-
-An entity specified by number (dec, hex, oct) is out of range (1-255).
-
-=item * malformed link LE<lt>E<gt>
-
-The link found cannot be parsed because it does not conform to the
-syntax described in L<perlpod>.
-
-=item * nonempty ZE<lt>E<gt>
-
-The C<ZE<lt>E<gt>> sequence is supposed to be empty.
-
-=item * empty XE<lt>E<gt>
-
-The index entry specified contains nothing but whitespace.
-
-=item * Spurious text after =pod / =cut
-
-The commands C<=pod> and C<=cut> do not take any arguments.
-
-=item * Spurious character(s) after =back
-
-The C<=back> command does not take any arguments.
-
-=back
-
-=head2 Warnings
-
-These may not necessarily cause trouble, but indicate mediocre style.
-
-=over 4
-
-=item * multiple occurrence of link target I<name>
-
-The POD file has some C<=item> and/or C<=head> commands that have
-the same text. Potential hyperlinks to such a text cannot be unique then.
-This warning is printed only with warning level greater than one.
-
-=item * line containing nothing but whitespace in paragraph
-
-There is some whitespace on a seemingly empty line. POD is very sensitive
-to such things, so this is flagged. B<vi> users switch on the B<list>
-option to avoid this problem.
-
-=begin _disabled_
-
-=item * file does not start with =head
-
-The file starts with a different POD directive than head.
-This is most probably something you do not want.
-
-=end _disabled_
-
-=item * previous =item has no contents
-
-There is a list C<=item> right above the flagged line that has no
-text contents. You probably want to delete empty items.
-
-=item * preceding non-item paragraph(s)
-
-A list introduced by C<=over> starts with a text or verbatim paragraph,
-but continues with C<=item>s. Move the non-item paragraph out of the
-C<=over>/C<=back> block.
-
-=item * =item type mismatch (I<one> vs. I<two>)
-
-A list started with e.g. a bullet-like C<=item> and continued with a
-numbered one. This is obviously inconsistent. For most translators the
-type of the I<first> C<=item> determines the type of the list.
-
-=item * I<N> unescaped C<E<lt>E<gt>> in paragraph
-
-Angle brackets not written as C<E<lt>ltE<gt>> and C<E<lt>gtE<gt>>
-can potentially cause errors as they could be misinterpreted as
-markup commands. This is only printed when the -warnings level is
-greater than 1.
-
-=item * Unknown entity
-
-A character entity was found that does not belong to the standard
-ISO set or the POD specials C<verbar> and C<sol>.
-
-=item * No items in =over
-
-The list opened with C<=over> does not contain any items.
-
-=item * No argument for =item
-
-C<=item> without any parameters is deprecated. It should either be followed
-by C<*> to indicate an unordered list, by a number (optionally followed
-by a dot) to indicate an ordered (numbered) list or simple text for a
-definition list.
-
-=item * empty section in previous paragraph
-
-The previous section (introduced by a C<=head> command) does not contain
-any text. This usually indicates that something is missing. Note: A
-C<=head1> followed immediately by C<=head2> does not trigger this warning.
-
-=item * Verbatim paragraph in NAME section
-
-The NAME section (C<=head1 NAME>) should consist of a single paragraph
-with the script/module name, followed by a dash `-' and a very short
-description of what the thing is good for.
-
-=item * =headI<n> without preceding higher level
-
-For example if there is a C<=head2> in the POD file prior to a
-C<=head1>.
-
-=back
-
-=head2 Hyperlinks
-
-There are some warnings with respect to malformed hyperlinks:
-
-=over 4
-
-=item * ignoring leading/trailing whitespace in link
-
-There is whitespace at the beginning or the end of the contents of
-LE<lt>...E<gt>.
-
-=item * (section) in '$page' deprecated
-
-There is a section detected in the page name of LE<lt>...E<gt>, e.g.
-C<LE<lt>passwd(2)E<gt>>. POD hyperlinks may point to POD documents only.
-Please write C<CE<lt>passwd(2)E<gt>> instead. Some formatters are able
-to expand this to appropriate code. For links to (builtin) functions,
-please say C<LE<lt>perlfunc/mkdirE<gt>>, without ().
-
-=item * alternative text/node '%s' contains non-escaped | or /
-
-The characters C<|> and C</> are special in the LE<lt>...E<gt> context.
-Although the hyperlink parser does its best to determine which "/" is
-text and which is a delimiter in case of doubt, one ought to escape
-these literal characters like this:
-
-  /     E<sol>
-  |     E<verbar>
-
-=back
-
-=head1 RETURN VALUE
-
-B<podchecker> returns the number of POD syntax errors found or -1 if
-there were no POD commands at all found in the file.
-
-=head1 EXAMPLES
-
-See L</SYNOPSIS>
-
-=head1 INTERFACE
-
-While checking, this module collects document properties, e.g. the nodes
-for hyperlinks (C<=headX>, C<=item>) and index entries (C<XE<lt>E<gt>>).
-POD translators can use this feature to syntax-check and get the nodes in
-a first pass before actually starting to convert. This is expensive in terms
-of execution time, but allows for very robust conversions.
-
-Since PodParser-1.24 the B<Pod::Checker> module uses only the B<poderror>
-method to print errors and warnings. The summary output (e.g.
-"Pod syntax OK") has been dropped from the module and has been included in
-B<podchecker> (the script). This allows users of B<Pod::Checker> to
-control completely the output behavior. Users of B<podchecker> (the script)
-get the well-known behavior.

-Pod::Find - find POD documents in directory trees
-
-=head1 SYNOPSIS
-
-  use Pod::Find qw(pod_find simplify_name);
-  my %pods = pod_find({ -verbose => 1, -inc => 1 });
-  foreach(keys %pods) {
-     print "found library POD `$pods{$_}' in $_\n";
-  }
-
-  print "podname=",simplify_name('a/b/c/mymodule.pod'),"\n";
-
-  $location = pod_where( { -inc => 1 }, "Pod::Find" );
-
-=head1 DESCRIPTION
-
-B<Pod::Find> provides a set of functions to locate POD files.  Note that
-no function is exported by default to avoid pollution of your namespace,
-so be sure to specify them in the B<use> statement if you need them:
-
-  use Pod::Find qw(pod_find);
-
-From this version on the typical SCM (software configuration management)
-files/directories like RCS, CVS, SCCS, .svn are ignored.

-@EXPORT_OK = qw(&pod_find &simplify_name &pod_where &contains_pod);

-
-=head2 C<pod_find( { %opts } , @directories )>
-
-The function B<pod_find> searches for POD documents in a given set of
-files and/or directories. It returns a hash with the file names as keys
-and the POD name as value. The POD name is derived from the file name
-and its position in the directory tree.
-
-E.g. when searching in F<$HOME/perl5lib>, the file
-F<$HOME/perl5lib/MyModule.pm> would get the POD name I<MyModule>,
-whereas F<$HOME/perl5lib/Myclass/Subclass.pm> would be
-I<Myclass::Subclass>. The name information can be used for POD
-translators.
-
-Only text files containing at least one valid POD command are found.
-
-A warning is printed if more than one POD file with the same POD name
-is found, e.g. F<CPAN.pm> in different directories. This usually
-indicates duplicate occurrences of modules in the I<@INC> search path.
-
-B<OPTIONS> The first argument for B<pod_find> may be a hash reference
-with options. The rest are either directories that are searched
-recursively or files.  The POD names of files are the plain basenames
-with any Perl-like extension (.pm, .pl, .pod) stripped.
-
-=over 4
-
-=item C<-verbose =E<gt> 1>
-
-Print progress information while scanning.
-
-=item C<-perl =E<gt> 1>
-
-Apply Perl-specific heuristics to find the correct PODs. This includes
-stripping Perl-like extensions, omitting subdirectories that are numeric
-but do I<not> match the current Perl interpreter's version id, suppressing
-F<site_perl> as a module hierarchy name etc.
-
-=item C<-script =E<gt> 1>
-
-Search for PODs in the current Perl interpreter's installation 
-B<scriptdir>. This is taken from the local L<Config|Config> module.
-
-=item C<-inc =E<gt> 1>
-
-Search for PODs in the current Perl interpreter's I<@INC> paths. This
-automatically considers paths specified in the C<PERL5LIB> environment
-as this is included in I<@INC> by the Perl interpreter itself.

-=head2 C<pod_where( { %opts }, $pod )>
-
-Returns the location of a pod document given a search directory
-and a module (e.g. C<File::Find>) or script (e.g. C<perldoc>) name.
-
-Options:
-
-=over 4
-
-=item C<-inc =E<gt> 1>
-
-Search @INC for the pod and also the C<scriptdir> defined in the
-L<Config|Config> module.
-
-=item C<-dirs =E<gt> [ $dir1, $dir2, ... ]>
-
-Reference to an array of search directories. These are searched in order
-before looking in C<@INC> (if B<-inc>). Current directory is used if
-none are specified.
-
-=item C<-verbose =E<gt> 1>
-
-List directories as they are searched
-
-=back
-
-Returns the full path of the first occurrence to the file.
-Package names (eg 'A::B') are automatically converted to directory
-names in the selected directory. (eg on unix 'A::B' is converted to
-'A/B'). Additionally, '.pm', '.pl' and '.pod' are appended to the
-search automatically if required.
-
-A subdirectory F<pod/> is also checked if it exists in any of the given
-search directories. This ensures that e.g. L<perlfunc|perlfunc> is
-found.
-
-It is assumed that if a module name is supplied, that that name
-matches the file name. Pods are not opened to check for the 'NAME'
-entry.
-
-A check is made to make sure that the file that is found does 
-contain some pod documentation.

-
-Pod::InputObjects - objects representing POD input paragraphs, commands, etc.
-
-=head1 SYNOPSIS
-
-    use Pod::InputObjects;
-
-=head1 REQUIRES
-
-perl5.004, Carp
-
-=head1 EXPORTS
-
-Nothing.
-
-=head1 DESCRIPTION
-
-This module defines some basic input objects used by B<Pod::Parser> when
-reading and parsing POD text from an input source. The following objects
-are defined:
-
-=over 4
-
-=begin __PRIVATE__
-
-=item package B<Pod::InputSource>
-
-An object corresponding to a source of POD input text. It is mostly a
-wrapper around a filehandle or C<IO::Handle>-type object (or anything
-that implements the C<getline()> method) which keeps track of some
-additional information relevant to the parsing of PODs.
-
-=end __PRIVATE__
-
-=item package B<Pod::Paragraph>
-
-An object corresponding to a paragraph of POD input text. It may be a
-plain paragraph, a verbatim paragraph, or a command paragraph (see
-L<perlpod>).
-
-=item package B<Pod::InteriorSequence>
-
-An object corresponding to an interior sequence command from the POD
-input text (see L<perlpod>).
-
-=item package B<Pod::ParseTree>
-
-An object corresponding to a tree of parsed POD text. Each "node" in
-a parse-tree (or I<ptree>) is either a text-string or a reference to
-a B<Pod::InteriorSequence> object. The nodes appear in the parse-tree
-in the order in which they were parsed from left-to-right.
-
-=back
-
-Each of these input objects are described in further detail in the
-sections which follow.

-
-=begin __PRIVATE__
-
-=head1 B<Pod::InputSource>
-
-This object corresponds to an input source or stream of POD
-documentation. When parsing PODs, it is necessary to associate and store
-certain context information with each input source. All of this
-information is kept together with the stream itself in one of these
-C<Pod::InputSource> objects. Each such object is merely a wrapper around
-an C<IO::Handle> object of some kind (or at least something that
-implements the C<getline()> method). They have the following
-methods/attributes:

-C<-name> is optional and specifies the name associated with the input
-handle (typically a file name).

-}
-
-=item $list-E<gt>file()
-
-Without argument, retrieves the file name the list is in. This must
-have been set before by either specifying B<-file> in the B<new()>
-method or by calling the B<file()> method with a scalar argument.
-

-
-Without argument, retrieves the line number where the list started.
-This must have been set before by either specifying B<-start> in the

-
-Without argument, retrieves the indent level of the list as specified
-in C<=over n>. This must have been set before by either specifying

-
-Without argument, retrieves a regular expression for simplifying the 
-individual item strings once the list type has been determined. Usage:
-E.g. when converting to HTML, one might strip the leading number in
-an ordered list as C<E<lt>OLE<gt>> already prints numbers itself.
-This must have been set before by either specifying
-B<-rx> in the B<new()> method or by calling the B<rx()> method

-C<LE<lt>...E<gt>> sequence, providing a simple interface for accessing the

-The B<new()> method can either be passed a set of key/value pairs or a single
-scalar value, namely the contents of a C<LE<lt>...E<gt>> sequence. An object
-of the class C<Pod::Hyperlink> is returned. The value C<undef> indicates a
-failure, the error message is stored in C<$@>.

-=head1 DESCRIPTION
-
-B<Pod::Parser> is a base class for creating POD filters and translators.
-It handles most of the effort involved with parsing the POD sections
-from an input stream, leaving subclasses free to be concerned only with
-performing the actual translation of text.
-
-B<Pod::Parser> parses PODs, and makes method calls to handle the various
-components of the POD. Subclasses of B<Pod::Parser> override these methods
-to translate the POD into whatever output format they desire.
-
-=head1 QUICK OVERVIEW
-
-To create a POD filter for translating POD documentation into some other
-format, you create a subclass of B<Pod::Parser> which typically overrides
-just the base class implementation for the following methods:
-
-=over 2
-
-=item *
-
-B<command()>
-
-=item *
-
-B<verbatim()>
-
-=item *
-
-B<textblock()>
-
-=item *
-
-B<interior_sequence()>
-
-=back
-
-You may also want to override the B<begin_input()> and B<end_input()>
-methods for your subclass (to perform any needed per-file and/or
-per-document initialization or cleanup).
-
-If you need to perform any preprocessing of input before it is parsed
-you may want to override one or more of B<preprocess_line()> and/or
-B<preprocess_paragraph()>.
-
-Sometimes it may be necessary to make more than one pass over the input
-files. If this is the case you have several options. You can make the
-first pass using B<Pod::Parser> and override your methods to store the
-intermediate results in memory somewhere for the B<end_pod()> method to
-process. You could use B<Pod::Parser> for several passes with an
-appropriate state variable to control the operation for each pass. If
-your input source can't be reset to start at the beginning, you can
-store it in some other structure as a string or an array and have that
-structure implement a B<getline()> method (which is all that
-B<parse_from_filehandle()> uses to read input).
-
-Feel free to add any member data fields you need to keep track of things
-like current font, indentation, horizontal or vertical position, or
-whatever else you like. Be sure to read L<"PRIVATE METHODS AND DATA">
-to avoid name collisions.
-
-For the most part, the B<Pod::Parser> base class should be able to
-do most of the input parsing for you and leave you free to worry about
-how to interpret the commands and translate the result.
-
-Note that all we have described here in this quick overview is the
-simplest most straightforward use of B<Pod::Parser> to do stream-based
-parsing. It is also possible to use the B<Pod::Parser::parse_text> function
-to do more sophisticated tree-based parsing. See L<"TREE-BASED PARSING">.
-
-=head1 PARSING OPTIONS
-
-A I<parse-option> is simply a named option of B<Pod::Parser> with a
-value that corresponds to a certain specified behavior. These various
-behaviors of B<Pod::Parser> may be enabled/disabled by setting
-or unsetting one or more I<parse-options> using the B<parseopts()> method.
-The set of currently accepted parse-options is as follows:
-
-=over 3
-
-=item B<-want_nonPODs> (default: unset)
-
-Normally (by default) B<Pod::Parser> will only provide access to
-the POD sections of the input. Input paragraphs that are not part
-of the POD-format documentation are not made available to the caller
-(not even using B<preprocess_paragraph()>). Setting this option to a
-non-empty, non-zero value will allow B<preprocess_paragraph()> to see
-non-POD sections of the input as well as POD sections. The B<cutting()>
-method can be used to determine if the corresponding paragraph is a POD
-paragraph, or some other input paragraph.
-
-=item B<-process_cut_cmd> (default: unset)
-
-Normally (by default) B<Pod::Parser> handles the C<=cut> POD directive
-by itself and does not pass it on to the caller for processing. Setting
-this option to a non-empty, non-zero value will cause B<Pod::Parser> to
-pass the C<=cut> directive to the caller just like any other POD command
-(and hence it may be processed by the B<command()> method).
-
-B<Pod::Parser> will still interpret the C<=cut> directive to mean that
-"cutting mode" has been (re)entered, but the caller will get a chance
-to capture the actual C<=cut> paragraph itself for whatever purpose
-it desires.
-
-=item B<-warnings> (default: unset)
-
-Normally (by default) B<Pod::Parser> recognizes a bare minimum of
-pod syntax errors and warnings and issues diagnostic messages
-for errors, but not for warnings. (Use B<Pod::Checker> to do more
-thorough checking of POD syntax.) Setting this option to a non-empty,
-non-zero value will cause B<Pod::Parser> to issue diagnostics for
-the few warnings it recognizes as well as the errors.

-=head1 RECOMMENDED SUBROUTINE/METHOD OVERRIDES
-
-B<Pod::Parser> provides several methods which most subclasses will probably
-want to override. These methods are as follows:
-
-=cut
-
-##---------------------------------------------------------------------------
-
-=head1 B<command()>
-
-            $parser->command($cmd,$text,$line_num,$pod_para);
-
-This method should be overridden by subclasses to take the appropriate
-action when a POD command paragraph (denoted by a line beginning with
-"=") is encountered. When such a POD directive is seen in the input,
-this method is called and is passed:
-
-=over 3
-
-=item C<$cmd>
-
-the name of the command for this POD paragraph
-
-=item C<$text>
-
-the paragraph text for the given POD paragraph command.
-
-=item C<$line_num>
-
-the line-number of the beginning of the paragraph
-
-=item C<$pod_para>
-
-a reference to a C<Pod::Paragraph> object which contains further
-information about the paragraph command (see L<Pod::InputObjects>
-for details).
-
-=back
-
-B<Note> that this method I<is> called for C<=pod> paragraphs.
-
-The base class implementation of this method simply treats the raw POD
-command as normal block of paragraph text (invoking the B<textblock()>
-method with the command paragraph).
-
-=cut
-
-sub command {
-    my ($self, $cmd, $text, $line_num, $pod_para)  = @_;
-    ## Just treat this like a textblock
-    $self->textblock($pod_para->raw_text(), $line_num, $pod_para);
-}
-
-##---------------------------------------------------------------------------
-
-=head1 B<verbatim()>
-
-            $parser->verbatim($text,$line_num,$pod_para);
-
-This method may be overridden by subclasses to take the appropriate
-action when a block of verbatim text is encountered. It is passed the
-following parameters:
-
-=over 3
-
-=item C<$text>
-
-the block of text for the verbatim paragraph
-
-=item C<$line_num>
-
-the line-number of the beginning of the paragraph
-
-=item C<$pod_para>
-
-a reference to a C<Pod::Paragraph> object which contains further
-information about the paragraph (see L<Pod::InputObjects>
-for details).
-
-=back
-
-The base class implementation of this method simply prints the textblock
-(unmodified) to the output filehandle.
-
-=cut
-
-sub verbatim {
-    my ($self, $text, $line_num, $pod_para) = @_;
-    my $out_fh = $self->{_OUTPUT};
-    print $out_fh $text;
-}
-
-##---------------------------------------------------------------------------
-
-=head1 B<textblock()>
-
-            $parser->textblock($text,$line_num,$pod_para);
-
-This method may be overridden by subclasses to take the appropriate
-action when a normal block of POD text is encountered (although the base
-class method will usually do what you want). It is passed the following
-parameters:
-
-=over 3
-
-=item C<$text>
-
-the block of text for the a POD paragraph
-
-=item C<$line_num>
-
-the line-number of the beginning of the paragraph
-
-=item C<$pod_para>
-
-a reference to a C<Pod::Paragraph> object which contains further
-information about the paragraph (see L<Pod::InputObjects>
-for details).
-
-=back
-
-In order to process interior sequences, subclasses implementations of
-this method will probably want to invoke either B<interpolate()> or
-B<parse_text()>, passing it the text block C<$text>, and the corresponding
-line number in C<$line_num>, and then perform any desired processing upon
-the returned result.
-
-The base class implementation of this method simply prints the text block
-as it occurred in the input stream).
-
-=cut
-
-sub textblock {
-    my ($self, $text, $line_num, $pod_para) = @_;
-    my $out_fh = $self->{_OUTPUT};
-    print $out_fh $self->interpolate($text, $line_num);
-}
-
-##---------------------------------------------------------------------------
-
-=head1 B<interior_sequence()>
-
-            $parser->interior_sequence($seq_cmd,$seq_arg,$pod_seq);
-
-This method should be overridden by subclasses to take the appropriate
-action when an interior sequence is encountered. An interior sequence is
-an embedded command within a block of text which appears as a command
-name (usually a single uppercase character) followed immediately by a
-string of text which is enclosed in angle brackets. This method is
-passed the sequence command C<$seq_cmd> and the corresponding text
-C<$seq_arg>. It is invoked by the B<interpolate()> method for each interior
-sequence that occurs in the string that it is passed. It should return
-the desired text string to be used in place of the interior sequence.
-The C<$pod_seq> argument is a reference to a C<Pod::InteriorSequence>
-object which contains further information about the interior sequence.
-Please see L<Pod::InputObjects> for details if you need to access this
-additional information.
-
-Subclass implementations of this method may wish to invoke the 
-B<nested()> method of C<$pod_seq> to see if it is nested inside
-some other interior-sequence (and if so, which kind).
-
-The base class implementation of the B<interior_sequence()> method
-simply returns the raw text of the interior sequence (as it occurred
-in the input) to the caller.
-
-=cut
-
-sub interior_sequence {
-    my ($self, $seq_cmd, $seq_arg, $pod_seq) = @_;
-    ## Just return the raw text of the interior sequence
-    return  $pod_seq->raw_text();

-
-=head1 OPTIONAL SUBROUTINE/METHOD OVERRIDES
-
-B<Pod::Parser> provides several methods which subclasses may want to override
-to perform any special pre/post-processing. These methods do I<not> have to
-be overridden, but it may be useful for subclasses to take advantage of them.
-
-=cut
-
-##---------------------------------------------------------------------------
-
-=head1 B<new()>
-
-            my $parser = Pod::Parser->new();
-
-This is the constructor for B<Pod::Parser> and its subclasses. You
-I<do not> need to override this method! It is capable of constructing
-subclass objects as well as base class objects, provided you use
-any of the following constructor invocation styles:
-
-    my $parser1 = MyParser->new();
-    my $parser2 = new MyParser();
-    my $parser3 = $parser2->new();
-
-where C<MyParser> is some subclass of B<Pod::Parser>.
-
-Using the syntax C<MyParser::new()> to invoke the constructor is I<not>
-recommended, but if you insist on being able to do this, then the
-subclass I<will> need to override the B<new()> constructor method. If
-you do override the constructor, you I<must> be sure to invoke the
-B<initialize()> method of the newly blessed object.
-
-Using any of the above invocations, the first argument to the
-constructor is always the corresponding package name (or object
-reference). No other arguments are required, but if desired, an
-associative array (or hash-table) my be passed to the B<new()>
-constructor, as in:
-
-    my $parser1 = MyParser->new( MYDATA => $value1, MOREDATA => $value2 );
-    my $parser2 = new MyParser( -myflag => 1 );
-
-All arguments passed to the B<new()> constructor will be treated as
-key/value pairs in a hash-table. The newly constructed object will be
-initialized by copying the contents of the given hash-table (which may
-have been empty). The B<new()> constructor for this class and all of its
-subclasses returns a blessed reference to the initialized object (hash-table).

-initializations.
-
-Note that if multiple files are parsed for a single POD document
-(perhaps the result of some future C<=include> directive) this method

-
-This method should be overridden by subclasses that wish to perform

-been determined whether or not it is part of a POD paragraph). The
-parameter C<$text> is the input line; and the parameter C<$line_num> is
-the line number of the corresponding text line.
-
-The value returned should correspond to the new text to use in its
-place.  If the empty string or an undefined value is returned then no
-further processing will be performed for this line.
-
-Please note that the B<preprocess_line()> method is invoked I<before>
-the B<preprocess_paragraph()> method. After all (possibly preprocessed)
-lines in a paragraph have been assembled together and it has been
-determined that the paragraph is part of the POD documentation from one

-
-This method should be overridden by subclasses that wish to perform any
-kind of preprocessing for each block (paragraph) of POD documentation
-that appears in the input stream. The parameter C<$text> is the POD
-paragraph from the input file; and the parameter C<$line_num> is the
-line number for the beginning of the corresponding paragraph.
-
-The value returned should correspond to the new text to use in its
-place If the empty string is returned or an undefined value is
-returned, then the given C<$text> is ignored (not processed).
-
-This method is invoked after gathering up all the lines in a paragraph
-and after determining the cutting state of the paragraph,
-but before trying to further parse or interpret them. After
-B<preprocess_paragraph()> returns, the current cutting state (which
-is returned by C<$self-E<gt>cutting()>) is examined. If it evaluates
-to true then input text (including the given C<$text>) is cut (not
-processed) until the next POD directive is encountered.
-
-Please note that the B<preprocess_line()> method is invoked I<before>
-the B<preprocess_paragraph()> method. After all (possibly preprocessed)
-lines in a paragraph have been assembled together and either it has been
-determined that the paragraph is part of the POD documentation from one

-=head1 METHODS FOR PARSING AND PROCESSING
-
-B<Pod::Parser> provides several methods to process input text. These
-methods typically won't need to be overridden (and in some cases they
-can't be overridden), but subclasses may want to invoke them to exploit
-their functionality.
-
-=cut
-
-##---------------------------------------------------------------------------
-
-=head1 B<parse_text()>
-
-            $ptree1 = $parser->parse_text($text, $line_num);
-            $ptree2 = $parser->parse_text({%opts}, $text, $line_num);
-            $ptree3 = $parser->parse_text(\%opts, $text, $line_num);
-
-This method is useful if you need to perform your own interpolation 
-of interior sequences and can't rely upon B<interpolate> to expand
-them in simple bottom-up order.
-
-The parameter C<$text> is a string or block of text to be parsed
-for interior sequences; and the parameter C<$line_num> is the
-line number corresponding to the beginning of C<$text>.
-
-B<parse_text()> will parse the given text into a parse-tree of "nodes."
-and interior-sequences.  Each "node" in the parse tree is either a
-text-string, or a B<Pod::InteriorSequence>.  The result returned is a
-parse-tree of type B<Pod::ParseTree>. Please see L<Pod::InputObjects>
-for more information about B<Pod::InteriorSequence> and B<Pod::ParseTree>.
-
-If desired, an optional hash-ref may be specified as the first argument
-to customize certain aspects of the parse-tree that is created and
-returned. The set of recognized option keywords are:
-
-=over 3
-
-=item B<-expand_seq> =E<gt> I<code-ref>|I<method-name>
-
-Normally, the parse-tree returned by B<parse_text()> will contain an
-unexpanded C<Pod::InteriorSequence> object for each interior-sequence
-encountered. Specifying B<-expand_seq> tells B<parse_text()> to "expand"
-every interior-sequence it sees by invoking the referenced function
-(or named method of the parser object) and using the return value as the
-expanded result.
-
-If a subroutine reference was given, it is invoked as:
-
-  &$code_ref( $parser, $sequence )
-
-and if a method-name was given, it is invoked as:
-
-  $parser->method_name( $sequence )
-
-where C<$parser> is a reference to the parser object, and C<$sequence>
-is a reference to the interior-sequence object.
-[I<NOTE>: If the B<interior_sequence()> method is specified, then it is
-invoked according to the interface specified in L<"interior_sequence()">].
-
-=item B<-expand_text> =E<gt> I<code-ref>|I<method-name>
-
-Normally, the parse-tree returned by B<parse_text()> will contain a
-text-string for each contiguous sequence of characters outside of an
-interior-sequence. Specifying B<-expand_text> tells B<parse_text()> to
-"preprocess" every such text-string it sees by invoking the referenced
-function (or named method of the parser object) and using the return value
-as the preprocessed (or "expanded") result. [Note that if the result is
-an interior-sequence, then it will I<not> be expanded as specified by the
-B<-expand_seq> option; Any such recursive expansion needs to be handled by
-the specified callback routine.]
-
-If a subroutine reference was given, it is invoked as:
-
-  &$code_ref( $parser, $text, $ptree_node )
-
-and if a method-name was given, it is invoked as:
-
-  $parser->method_name( $text, $ptree_node )
-
-where C<$parser> is a reference to the parser object, C<$text> is the
-text-string encountered, and C<$ptree_node> is a reference to the current
-node in the parse-tree (usually an interior-sequence object or else the
-top-level node of the parse-tree).
-
-=item B<-expand_ptree> =E<gt> I<code-ref>|I<method-name>
-
-Rather than returning a C<Pod::ParseTree>, pass the parse-tree as an
-argument to the referenced subroutine (or named method of the parser
-object) and return the result instead of the parse-tree object.
-
-If a subroutine reference was given, it is invoked as:
-
-  &$code_ref( $parser, $ptree )
-
-and if a method-name was given, it is invoked as:
-
-  $parser->method_name( $ptree )
-
-where C<$parser> is a reference to the parser object, and C<$ptree>
-is a reference to the parse-tree object.

-            $parser->errorsub("method_name");
-            $parser->errorsub(\&warn_user);
-            $parser->errorsub(sub { print STDERR, @_ });
-
-Specifies the method or subroutine to use when printing error messages
-about POD syntax. The supplied method/subroutine I<must> return TRUE upon
-successful printing of the message. If C<undef> is given, then the B<carp>
-builtin is used to issue error messages (this is the default behavior).
-
-            my $errorsub = $parser->errorsub()

-                or (defined $errorsub) and $parser->$errorsub($errmsg)
-                    or  carp($errmsg);

-used to print error messages. Returns C<undef> if the B<carp> builtin
-is used to issue error messages (this is the default behavior).

-Returns the current C<cutting> state: a boolean-valued scalar which
-evaluates to true if text from the input file is currently being "cut"
-(meaning it is I<not> considered part of the POD document).

-            my %opts = $parser->parseopts();
-            $opts{'-want_nonPODs}' and print "-want_nonPODs\n";
-
-When invoked using a single string, B<parseopts> treats the string as the
-name of a parse-option and returns its corresponding value if it exists
-(returns C<undef> if it doesn't).
-
-            ## Did we ask to see '=cut' paragraphs?
-            my $want_cut = $parser->parseopts('-process_cut_cmd');
-            $want_cut and print "-process_cut_cmd\n";
-
-When invoked with multiple arguments, B<parseopts> treats them as
-key/value pairs and the specified parse-option names are set to the
-given values. Any unspecified parse-options are unaffected.
-
-            ## Set them back to the default
-            $parser->parseopts(-warnings => 0);
-
-When passed a single hash-ref, B<parseopts> uses that hash to completely
-reset the existing parse-options, all previous parse-option values
-are lost.
-
-            ## Reset all options to default 
-            $parser->parseopts( { } );

-stream and then return to parsing the previous input stream. Each input
-stream to be parsed is pushed onto the end of this input stack
-before any of its input is read. The input stream that is currently
-being parsed is always at the end (or top) of the input stack. When an
-input stream has been exhausted, it is popped off the end of the
-input stack.
-
-Each element on this input stack is a reference to C<Pod::InputSource>
-object. Please see L<Pod::InputObjects> for more details.

-=head1 TREE-BASED PARSING
-
-If straightforward stream-based parsing wont meet your needs (as is
-likely the case for tasks such as translating PODs into structured
-markup languages like HTML and XML) then you may need to take the
-tree-based approach. Rather than doing everything in one pass and
-calling the B<interpolate()> method to expand sequences into text, it
-may be desirable to instead create a parse-tree using the B<parse_text()>
-method to return a tree-like structure which may contain an ordered
-list of children (each of which may be a text-string, or a similar
-tree-like structure).
-
-Pay special attention to L<"METHODS FOR PARSING AND PROCESSING"> and
-to the objects described in L<Pod::InputObjects>. The former describes
-the gory details and parameters for how to customize and extend the
-parsing behavior of B<Pod::Parser>. B<Pod::InputObjects> provides
-several objects that may all be used interchangeably as parse-trees. The
-most obvious one is the B<Pod::ParseTree> object. It defines the basic
-interface and functionality that all things trying to be a POD parse-tree
-should do. A B<Pod::ParseTree> is defined such that each "node" may be a
-text-string, or a reference to another parse-tree.  Each B<Pod::Paragraph>
-object and each B<Pod::InteriorSequence> object also supports the basic
-parse-tree interface.
-
-The B<parse_text()> method takes a given paragraph of text, and
-returns a parse-tree that contains one or more children, each of which
-may be a text-string, or an InteriorSequence object. There are also
-callback-options that may be passed to B<parse_text()> to customize
-the way it expands or transforms interior-sequences, as well as the
-returned result. These callbacks can be used to create a parse-tree
-with custom-made objects (which may or may not support the parse-tree
-interface, depending on how you choose to do it).
-
-If you wish to turn an entire POD document into a parse-tree, that process
-is fairly straightforward. The B<parse_text()> method is the key to doing
-this successfully. Every paragraph-callback (i.e. the polymorphic methods
-for B<command()>, B<verbatim()>, and B<textblock()> paragraphs) takes
-a B<Pod::Paragraph> object as an argument. Each paragraph object has a
-B<parse_tree()> method that can be used to get or set a corresponding
-parse-tree. So for each of those paragraph-callback methods, simply call
-B<parse_text()> with the options you desire, and then use the returned
-parse-tree to assign to the given paragraph object.
-
-That gives you a parse-tree for each paragraph - so now all you need is
-an ordered list of paragraphs. You can maintain that yourself as a data
-element in the object/hash. The most straightforward way would be simply
-to use an array-ref, with the desired set of custom "options" for each
-invocation of B<parse_text>. Let's assume the desired option-set is
-given by the hash C<%options>. Then we might do something like the
-following:
-
-    package MyPodParserTree;
-
-    @ISA = qw( Pod::Parser );
-
-    ...
-
-    sub begin_pod {
-        my $self = shift;
-        $self->{'-paragraphs'} = [];  ## initialize paragraph list
-    }
-
-    sub command { 
-        my ($parser, $command, $paragraph, $line_num, $pod_para) = @_;
-        my $ptree = $parser->parse_text({%options}, $paragraph, ...);
-        $pod_para->parse_tree( $ptree );
-        push @{ $self->{'-paragraphs'} }, $pod_para;
-    }
-
-    sub verbatim { 
-        my ($parser, $paragraph, $line_num, $pod_para) = @_;
-        push @{ $self->{'-paragraphs'} }, $pod_para;
-    }
-
-    sub textblock { 
-        my ($parser, $paragraph, $line_num, $pod_para) = @_;
-        my $ptree = $parser->parse_text({%options}, $paragraph, ...);
-        $pod_para->parse_tree( $ptree );
-        push @{ $self->{'-paragraphs'} }, $pod_para;
-    }
-
-    ...
-
-    package main;
-    ...
-    my $parser = new MyPodParserTree(...);
-    $parser->parse_from_file(...);
-    my $paragraphs_ref = $parser->{'-paragraphs'};
-
-Of course, in this module-author's humble opinion, I'd be more inclined to
-use the existing B<Pod::ParseTree> object than a simple array. That way
-everything in it, paragraphs and sequences, all respond to the same core
-interface for all parse-tree nodes. The result would look something like:
-
-    package MyPodParserTree2;
-
-    ...
-
-    sub begin_pod {
-        my $self = shift;
-        $self->{'-ptree'} = new Pod::ParseTree;  ## initialize parse-tree
-    }
-
-    sub parse_tree {
-        ## convenience method to get/set the parse-tree for the entire POD
-        (@_ > 1)  and  $_[0]->{'-ptree'} = $_[1];
-        return $_[0]->{'-ptree'};
-    }
-
-    sub command { 
-        my ($parser, $command, $paragraph, $line_num, $pod_para) = @_;
-        my $ptree = $parser->parse_text({<<options>>}, $paragraph, ...);
-        $pod_para->parse_tree( $ptree );
-        $parser->parse_tree()->append( $pod_para );
-    }
-
-    sub verbatim { 
-        my ($parser, $paragraph, $line_num, $pod_para) = @_;
-        $parser->parse_tree()->append( $pod_para );
-    }
-
-    sub textblock { 
-        my ($parser, $paragraph, $line_num, $pod_para) = @_;
-        my $ptree = $parser->parse_text({<<options>>}, $paragraph, ...);
-        $pod_para->parse_tree( $ptree );
-        $parser->parse_tree()->append( $pod_para );
-    }
-
-    ...
-
-    package main;
-    ...
-    my $parser = new MyPodParserTree2(...);
-    $parser->parse_from_file(...);
-    my $ptree = $parser->parse_tree;
-    ...
-
-Now you have the entire POD document as one great big parse-tree. You
-can even use the B<-expand_seq> option to B<parse_text> to insert
-whole different kinds of objects. Just don't expect B<Pod::Parser>
-to know what to do with them after that. That will need to be in your
-code. Or, alternatively, you can insert any object you like so long as
-it conforms to the B<Pod::ParseTree> interface.
-
-One could use this to create subclasses of B<Pod::Paragraphs> and
-B<Pod::InteriorSequences> for specific commands (or to create your own
-custom node-types in the parse-tree) and add some kind of B<emit()>
-method to each custom node/subclass object in the tree. Then all you'd
-need to do is recursively walk the tree in the desired order, processing
-the children (most likely from left to right) by formatting them if
-they are text-strings, or by calling their B<emit()> method if they
-are objects/references.
-
-=head1 CAVEATS
-
-Please note that POD has the notion of "paragraphs": this is something
-starting I<after> a blank (read: empty) line, with the single exception
-of the file start, which is also starting a paragraph. That means that
-especially a command (e.g. C<=head1>) I<must> be preceded with a blank
-line; C<__END__> is I<not> a blank line.

-=head1 NAME
-
-Pod::PlainText - Convert POD data to formatted ASCII text
-
-=head1 SYNOPSIS
-
-    use Pod::PlainText;
-    my $parser = Pod::PlainText->new (sentence => 0, width => 78);
-
-    # Read POD from STDIN and write to STDOUT.
-    $parser->parse_from_filehandle;
-
-    # Read POD from file.pod and write to file.txt.
-    $parser->parse_from_file ('file.pod', 'file.txt');
-
-=head1 DESCRIPTION
-
-Pod::PlainText is a module that can convert documentation in the POD format (the
-preferred language for documenting Perl) into formatted ASCII.  It uses no
-special formatting controls or codes whatsoever, and its output is therefore
-suitable for nearly any device.
-
-As a derived class from Pod::Parser, Pod::PlainText supports the same methods and
-interfaces.  See L<Pod::Parser> for all the details; briefly, one creates a
-new parser with C<Pod::PlainText-E<gt>new()> and then calls either
-parse_from_filehandle() or parse_from_file().
-
-new() can take options, in the form of key/value pairs, that control the
-behavior of the parser.  The currently recognized options are:
-
-=over 4
-
-=item alt
-
-If set to a true value, selects an alternate output format that, among other
-things, uses a different heading style and marks C<=item> entries with a
-colon in the left margin.  Defaults to false.
-
-=item indent
-
-The number of spaces to indent regular text, and the default indentation for
-C<=over> blocks.  Defaults to 4.
-
-=item loose
-
-If set to a true value, a blank line is printed after a C<=headN> headings.
-If set to false (the default), no blank line is printed after C<=headN>.
-This is the default because it's the expected formatting for manual pages;
-if you're formatting arbitrary text documents, setting this to true may
-result in more pleasing output.
-
-=item sentence
-
-If set to a true value, Pod::PlainText will assume that each sentence ends in two
-spaces, and will try to preserve that spacing.  If set to false, all
-consecutive whitespace in non-verbatim paragraphs is compressed into a
-single space.  Defaults to true.
-
-=item width
-
-The column at which to wrap text on the right-hand side.  Defaults to 76.
-
-=back
-
-The standard Pod::Parser method parse_from_filehandle() takes up to two
-arguments, the first being the file handle to read POD from and the second
-being the file handle to write the formatted output to.  The first defaults
-to STDIN if not given, and the second defaults to STDOUT.  The method
-parse_from_file() is almost identical, except that its two arguments are the
-input and output disk files instead.  See L<Pod::Parser> for the specific
-details.
-
-=head1 DIAGNOSTICS
-
-=over 4
-
-=item Bizarre space in item
-
-(W) Something has gone wrong in internal C<=item> processing.  This message
-indicates a bug in Pod::PlainText; you should never see it.
-
-=item Can't open %s for reading: %s
-
-(F) Pod::PlainText was invoked via the compatibility mode pod2text() interface
-and the input file it was given could not be opened.
-
-=item Unknown escape: %s
-
-(W) The POD source contained an C<EE<lt>E<gt>> escape that Pod::PlainText didn't
-know about.
-
-=item Unknown sequence: %s
-
-(W) The POD source contained a non-standard internal sequence (something of
-the form C<XE<lt>E<gt>>) that Pod::PlainText didn't know about.
-
-=item Unmatched =back
-
-(W) Pod::PlainText encountered a C<=back> command that didn't correspond to an
-C<=over> command.
-
-=back
-
-=head1 RESTRICTIONS
-
-Embedded Ctrl-As (octal 001) in the input will be mapped to spaces on
-output, due to an internal implementation detail.
-
-=head1 NOTES
-
-This is a replacement for an earlier Pod::Text module written by Tom
-Christiansen.  It has a revamped interface, since it now uses Pod::Parser,
-but an interface roughly compatible with the old Pod::Text::pod2text()
-function is still available.  Please change to the new calling convention,
-though.
-
-The original Pod::Text contained code to do formatting via termcap
-sequences, although it wasn't turned on by default and it was problematic to
-get it to work at all.  This rewrite doesn't even try to do that, but a
-subclass of it does.  Look for L<Pod::Text::Termcap|Pod::Text::Termcap>.

-podselect()
-
-=head1 DESCRIPTION
-
-B<podselect()> is a function which will extract specified sections of
-pod documentation from an input stream. This ability is provided by the
-B<Pod::Select> module which is a subclass of B<Pod::Parser>.
-B<Pod::Select> provides a method named B<select()> to specify the set of
-POD sections to select for processing/printing. B<podselect()> merely
-creates a B<Pod::Select> object and then invokes the B<podselect()>
-followed by B<parse_from_file()>.
-
-=head1 SECTION SPECIFICATIONS
-
-B<podselect()> and B<Pod::Select::select()> may be given one or more
-"section specifications" to restrict the text processed to only the
-desired set of sections and their corresponding subsections.  A section
-specification is a string containing one or more Perl-style regular
-expressions separated by forward slashes ("/").  If you need to use a
-forward slash literally within a section title you can escape it with a
-backslash ("\/").
-
-The formal syntax of a section specification is:
-
-=over 4
-
-=item *
-
-I<head1-title-regex>/I<head2-title-regex>/...
-
-=back
-
-Any omitted or empty regular expressions will default to ".*".
-Please note that each regular expression given is implicitly
-anchored by adding "^" and "$" to the beginning and end.  Also, if a
-given regular expression starts with a "!" character, then the
-expression is I<negated> (so C<!foo> would match anything I<except>
-C<foo>).
-
-Some example section specifications follow.
-
-=over 4
-
-=item *
-
-Match the C<NAME> and C<SYNOPSIS> sections and all of their subsections:
-
-C<NAME|SYNOPSIS>
-
-=item *
-
-Match only the C<Question> and C<Answer> subsections of the C<DESCRIPTION>
-section:
-
-C<DESCRIPTION/Question|Answer>
-
-=item *
-
-Match the C<Comments> subsection of I<all> sections:
-
-C</Comments>
-
-=item *
-
-Match all subsections of C<DESCRIPTION> I<except> for C<Comments>:
-
-C<DESCRIPTION/!Comments>
-
-=item *
-
-Match the C<DESCRIPTION> section but do I<not> match any of its subsections:
-
-C<DESCRIPTION/!.+>
-
-=item *
-
-Match all top level sections but none of their subsections:
-
-C</!.+>
-
-=back 
-
-=begin _NOT_IMPLEMENTED_
-
-=head1 RANGE SPECIFICATIONS
-
-B<podselect()> and B<Pod::Select::select()> may be given one or more
-"range specifications" to restrict the text processed to only the
-desired ranges of paragraphs in the desired set of sections. A range
-specification is a string containing a single Perl-style regular
-expression (a regex), or else two Perl-style regular expressions
-(regexs) separated by a ".." (Perl's "range" operator is "..").
-The regexs in a range specification are delimited by forward slashes
-("/").  If you need to use a forward slash literally within a regex you
-can escape it with a backslash ("\/").
-
-The formal syntax of a range specification is:
-
-=over 4
-
-=item *
-
-/I<start-range-regex>/[../I<end-range-regex>/]
-
-=back
-
-Where each the item inside square brackets (the ".." followed by the
-end-range-regex) is optional. Each "range-regex" is of the form:
-
-    =cmd-expr text-expr
-
-Where I<cmd-expr> is intended to match the name of one or more POD
-commands, and I<text-expr> is intended to match the paragraph text for
-the command. If a range-regex is supposed to match a POD command, then
-the first character of the regex (the one after the initial '/')
-absolutely I<must> be a single '=' character; it may not be anything
-else (not even a regex meta-character) if it is supposed to match
-against the name of a POD command.
-
-If no I<=cmd-expr> is given then the text-expr will be matched against
-plain textblocks unless it is preceded by a space, in which case it is
-matched against verbatim text-blocks. If no I<text-expr> is given then
-only the command-portion of the paragraph is matched against.
-
-Note that these two expressions are each implicitly anchored. This
-means that when matching against the command-name, there will be an
-implicit '^' and '$' around the given I<=cmd-expr>; and when matching
-against the paragraph text there will be an implicit '\A' and '\Z'
-around the given I<text-expr>.
-
-Unlike with section-specs, the '!' character does I<not> have any special
-meaning (negation or otherwise) at the beginning of a range-spec!
-
-Some example range specifications follow.
-
-=over 4
-
-=item
-Match all C<=for html> paragraphs:
-
-C</=for html/>
-
-=item
-Match all paragraphs between C<=begin html> and C<=end html>
-(note that this will I<not> work correctly if such sections
-are nested):
-
-C</=begin html/../=end html/>
-
-=item
-Match all paragraphs between the given C<=item> name until the end of the
-current section:
-
-C</=item mine/../=head\d/>
-
-=item
-Match all paragraphs between the given C<=item> until the next item, or
-until the end of the itemized list (note that this will I<not> work as
-desired if the item contains an itemized list nested within it):
-
-C</=item mine/../=(item|back)/>

-=head1 PRIVATE METHODS AND DATA
-
-B<Pod::Select> makes uses a number of internal methods and data fields
-which clients should not need to see or use. For the sake of avoiding
-name collisions with client data and methods, these methods and fields
-are briefly discussed here. Determined hackers may obtain further
-information about them by reading the B<Pod::Select> source code.
-
-Private data fields are stored in the hash-object whose reference is
-returned by the B<new()> constructor for this class. The names of all

-=head1 NAME
-
-Pod::Usage, pod2usage() - print a usage message from embedded pod documentation
-
-=head1 SYNOPSIS
-
-  use Pod::Usage
-
-  my $message_text  = "This text precedes the usage message.";
-  my $exit_status   = 2;          ## The exit status to use
-  my $verbose_level = 0;          ## The verbose level to use
-  my $filehandle    = \*STDERR;   ## The filehandle to write to
-
-  pod2usage($message_text);
-
-  pod2usage($exit_status);
-
-  pod2usage( { -message => $message_text ,
-               -exitval => $exit_status  ,  
-               -verbose => $verbose_level,  
-               -output  => $filehandle } );
-
-  pod2usage(   -msg     => $message_text ,
-               -exitval => $exit_status  ,  
-               -verbose => $verbose_level,  
-               -output  => $filehandle   );
-
-  pod2usage(   -verbose => 2,
-               -noperldoc => 1  )
-
-=head1 ARGUMENTS
-
-B<pod2usage> should be given either a single argument, or a list of
-arguments corresponding to an associative array (a "hash"). When a single
-argument is given, it should correspond to exactly one of the following:
-
-=over 4
-
-=item *
-
-A string containing the text of a message to print I<before> printing
-the usage message
-
-=item *
-
-A numeric value corresponding to the desired exit status
-
-=item *
-
-A reference to a hash
-
-=back
-
-If more than one argument is given then the entire argument list is
-assumed to be a hash.  If a hash is supplied (either as a reference or
-as a list) it should contain one or more elements with the following
-keys:
-
-=over 4
-
-=item C<-message>
-
-=item C<-msg>
-
-The text of a message to print immediately prior to printing the
-program's usage message. 
-
-=item C<-exitval>
-
-The desired exit status to pass to the B<exit()> function.
-This should be an integer, or else the string "NOEXIT" to
-indicate that control should simply be returned without
-terminating the invoking process.
-
-=item C<-verbose>
-
-The desired level of "verboseness" to use when printing the usage
-message. If the corresponding value is 0, then only the "SYNOPSIS"
-section of the pod documentation is printed. If the corresponding value
-is 1, then the "SYNOPSIS" section, along with any section entitled
-"OPTIONS", "ARGUMENTS", or "OPTIONS AND ARGUMENTS" is printed.  If the
-corresponding value is 2 or more then the entire manpage is printed.
-
-The special verbosity level 99 requires to also specify the -sections
-parameter; then these sections are extracted (see L<Pod::Select>)
-and printed.
-
-=item C<-sections>
-
-A string representing a selection list for sections to be printed
-when -verbose is set to 99, e.g. C<"NAME|SYNOPSIS|DESCRIPTION|VERSION">.
-
-Alternatively, an array reference of section specifications can be used:
-
-  pod2usage(-verbose => 99, 
-            -sections => [ qw(fred fred/subsection) ] );
-
-=item C<-output>
-
-A reference to a filehandle, or the pathname of a file to which the
-usage message should be written. The default is C<\*STDERR> unless the
-exit value is less than 2 (in which case the default is C<\*STDOUT>).
-
-=item C<-input>
-
-A reference to a filehandle, or the pathname of a file from which the
-invoking script's pod documentation should be read.  It defaults to the
-file indicated by C<$0> (C<$PROGRAM_NAME> for users of F<English.pm>).
-
-If you are calling B<pod2usage()> from a module and want to display
-that module's POD, you can use this:
-
-  use Pod::Find qw(pod_where);
-  pod2usage( -input => pod_where({-inc => 1}, __PACKAGE__) );
-
-=item C<-pathlist>
-
-A list of directory paths. If the input file does not exist, then it
-will be searched for in the given directory list (in the order the
-directories appear in the list). It defaults to the list of directories
-implied by C<$ENV{PATH}>. The list may be specified either by a reference
-to an array, or by a string of directory paths which use the same path
-separator as C<$ENV{PATH}> on your system (e.g., C<:> for Unix, C<;> for
-MSWin32 and DOS).
-
-=item C<-noperldoc>
-
-By default, Pod::Usage will call L<perldoc> when -verbose >= 2 is
-specified. This does not work well e.g. if the script was packed
-with L<PAR>. The -noperldoc option suppresses the external call to
-L<perldoc> and uses the simple text formatter (L<Pod::Text>) to 
-output the POD.
-
-=back
-
-=head1 DESCRIPTION
-
-B<pod2usage> will print a usage message for the invoking script (using
-its embedded pod documentation) and then exit the script with the
-desired exit status. The usage message printed may have any one of three
-levels of "verboseness": If the verbose level is 0, then only a synopsis
-is printed. If the verbose level is 1, then the synopsis is printed
-along with a description (if present) of the command line options and
-arguments. If the verbose level is 2, then the entire manual page is
-printed.
-
-Unless they are explicitly specified, the default values for the exit
-status, verbose level, and output stream to use are determined as
-follows:
-
-=over 4
-
-=item *
-
-If neither the exit status nor the verbose level is specified, then the
-default is to use an exit status of 2 with a verbose level of 0.
-
-=item *
-
-If an exit status I<is> specified but the verbose level is I<not>, then the
-verbose level will default to 1 if the exit status is less than 2 and
-will default to 0 otherwise.
-
-=item *
-
-If an exit status is I<not> specified but verbose level I<is> given, then
-the exit status will default to 2 if the verbose level is 0 and will
-default to 1 otherwise.
-
-=item *
-
-If the exit status used is less than 2, then output is printed on
-C<STDOUT>.  Otherwise output is printed on C<STDERR>.
-
-=back
-
-Although the above may seem a bit confusing at first, it generally does
-"the right thing" in most situations.  This determination of the default
-values to use is based upon the following typical Unix conventions:
-
-=over 4
-
-=item *
-
-An exit status of 0 implies "success". For example, B<diff(1)> exits
-with a status of 0 if the two files have the same contents.
-
-=item *
-
-An exit status of 1 implies possibly abnormal, but non-defective, program
-termination.  For example, B<grep(1)> exits with a status of 1 if
-it did I<not> find a matching line for the given regular expression.
-
-=item *
-
-An exit status of 2 or more implies a fatal error. For example, B<ls(1)>
-exits with a status of 2 if you specify an illegal (unknown) option on
-the command line.
-
-=item *
-
-Usage messages issued as a result of bad command-line syntax should go
-to C<STDERR>.  However, usage messages issued due to an explicit request
-to print usage (like specifying B<-help> on the command line) should go
-to C<STDOUT>, just in case the user wants to pipe the output to a pager
-(such as B<more(1)>).
-
-=item *
-
-If program usage has been explicitly requested by the user, it is often
-desirable to exit with a status of 1 (as opposed to 0) after issuing
-the user-requested usage message.  It is also desirable to give a
-more verbose description of program usage in this case.
-
-=back
-
-B<pod2usage> doesn't force the above conventions upon you, but it will
-use them by default if you don't expressly tell it to do otherwise.  The
-ability of B<pod2usage()> to accept a single number or a string makes it
-convenient to use as an innocent looking error message handling function:
-
-    use Pod::Usage;
-    use Getopt::Long;
-
-    ## Parse options
-    GetOptions("help", "man", "flag1")  ||  pod2usage(2);
-    pod2usage(1)  if ($opt_help);
-    pod2usage(-verbose => 2)  if ($opt_man);
-
-    ## Check for too many filenames
-    pod2usage("$0: Too many files given.\n")  if (@ARGV > 1);
-
-Some user's however may feel that the above "economy of expression" is
-not particularly readable nor consistent and may instead choose to do
-something more like the following:
-
-    use Pod::Usage;
-    use Getopt::Long;
-
-    ## Parse options
-    GetOptions("help", "man", "flag1")  ||  pod2usage(-verbose => 0);
-    pod2usage(-verbose => 1)  if ($opt_help);
-    pod2usage(-verbose => 2)  if ($opt_man);
-
-    ## Check for too many filenames
-    pod2usage(-verbose => 2, -message => "$0: Too many files given.\n")
-        if (@ARGV > 1);
-
-As with all things in Perl, I<there's more than one way to do it>, and
-B<pod2usage()> adheres to this philosophy.  If you are interested in
-seeing a number of different ways to invoke B<pod2usage> (although by no
-means exhaustive), please refer to L<"EXAMPLES">.
-
-=head1 EXAMPLES
-
-Each of the following invocations of C<pod2usage()> will print just the
-"SYNOPSIS" section to C<STDERR> and will exit with a status of 2:
-
-    pod2usage();
-
-    pod2usage(2);
-
-    pod2usage(-verbose => 0);
-
-    pod2usage(-exitval => 2);
-
-    pod2usage({-exitval => 2, -output => \*STDERR});
-
-    pod2usage({-verbose => 0, -output  => \*STDERR});
-
-    pod2usage(-exitval => 2, -verbose => 0);
-
-    pod2usage(-exitval => 2, -verbose => 0, -output => \*STDERR);
-
-Each of the following invocations of C<pod2usage()> will print a message
-of "Syntax error." (followed by a newline) to C<STDERR>, immediately
-followed by just the "SYNOPSIS" section (also printed to C<STDERR>) and
-will exit with a status of 2:
-
-    pod2usage("Syntax error.");
-
-    pod2usage(-message => "Syntax error.", -verbose => 0);
-
-    pod2usage(-msg  => "Syntax error.", -exitval => 2);
-
-    pod2usage({-msg => "Syntax error.", -exitval => 2, -output => \*STDERR});
-
-    pod2usage({-msg => "Syntax error.", -verbose => 0, -output => \*STDERR});
-
-    pod2usage(-msg  => "Syntax error.", -exitval => 2, -verbose => 0);
-
-    pod2usage(-message => "Syntax error.",
-              -exitval => 2,
-              -verbose => 0,
-              -output  => \*STDERR);
-
-Each of the following invocations of C<pod2usage()> will print the
-"SYNOPSIS" section and any "OPTIONS" and/or "ARGUMENTS" sections to
-C<STDOUT> and will exit with a status of 1:
-
-    pod2usage(1);
-
-    pod2usage(-verbose => 1);
-
-    pod2usage(-exitval => 1);
-
-    pod2usage({-exitval => 1, -output => \*STDOUT});
-
-    pod2usage({-verbose => 1, -output => \*STDOUT});
-
-    pod2usage(-exitval => 1, -verbose => 1);
-
-    pod2usage(-exitval => 1, -verbose => 1, -output => \*STDOUT});
-
-Each of the following invocations of C<pod2usage()> will print the
-entire manual page to C<STDOUT> and will exit with a status of 1:
-
-    pod2usage(-verbose  => 2);
-
-    pod2usage({-verbose => 2, -output => \*STDOUT});
-
-    pod2usage(-exitval  => 1, -verbose => 2);
-
-    pod2usage({-exitval => 1, -verbose => 2, -output => \*STDOUT});
-
-=head2 Recommended Use
-
-Most scripts should print some type of usage message to C<STDERR> when a
-command line syntax error is detected. They should also provide an
-option (usually C<-H> or C<-help>) to print a (possibly more verbose)
-usage message to C<STDOUT>. Some scripts may even wish to go so far as to
-provide a means of printing their complete documentation to C<STDOUT>
-(perhaps by allowing a C<-man> option). The following complete example
-uses B<Pod::Usage> in combination with B<Getopt::Long> to do all of these
-things:
-
-    use Getopt::Long;
-    use Pod::Usage;
-
-    my $man = 0;
-    my $help = 0;
-    ## Parse options and print usage if there is a syntax error,
-    ## or if usage was explicitly requested.
-    GetOptions('help|?' => \$help, man => \$man) or pod2usage(2);
-    pod2usage(1) if $help;
-    pod2usage(-verbose => 2) if $man;
-
-    ## If no arguments were given, then allow STDIN to be used only
-    ## if it's not connected to a terminal (otherwise print usage)
-    pod2usage("$0: No files given.")  if ((@ARGV == 0) && (-t STDIN));

-    B<This program> will read the given input file(s) and do something
-    useful with the contents thereof.
-
-    =cut
-
-=head1 CAVEATS
-
-By default, B<pod2usage()> will use C<$0> as the path to the pod input
-file.  Unfortunately, not all systems on which Perl runs will set C<$0>
-properly (although if C<$0> isn't found, B<pod2usage()> will search
-C<$ENV{PATH}> or else the list specified by the C<-pathlist> option).
-If this is the case for your system, you may need to explicitly specify
-the path to the pod docs for the invoking script using something
-similar to the following:
-
-    pod2usage(-exitval => 2, -input => "/path/to/your/pod/docs");
-
-In the pathological case that a script is called via a relative path
-I<and> the script itself changes the current working directory
-(see L<perlfunc/chdir>) I<before> calling pod2usage, Pod::Usage will
-fail even on robust platforms. Don't do that.
