+1. Don't do this from the root of the bzr repo. fatpack tries to be clever
+   and inlines everything under lib/
+2. mkdir lib/ is to get around a bug(?) in fatpack
+3. these two lines are safe to ignore:
+File /tmp/pod2rst/fatlib/darwin-thread-multi-2level/auto/HTML/Parser/Parser.bs isn't a .pm file - can't pack this and if you hoped we were going to things may not be what you expected later

+  =head1 DESCRIPTION
+  
+  This module implements a parser to convert Pod documents into a simple
+  object model form known hereafter as the Pod Object Model.  The object
+  model is generated as a hierarchical tree of nodes, each of which
+  represents a different element of the original document.  The tree can
+  be walked manually and the nodes examined, printed or otherwise
+  manipulated.  In addition, Pod::POM supports and provides view objects
+  which can automatically traverse the tree, or section thereof, and
+  generate an output representation in one form or another.
+  
+  Let's look at a typical Pod document by way of example.

+      =head1 AUTHOR
+  
+      My::Module was written by me E<lt>me@here.orgE<gt>
+  
+  This document contains 3 main sections, NAME, DESCRIPTION and 
+  AUTHOR, each of which is delimited by an opening C<=head1> tag.
+  NAME and AUTHOR each contain only a single line of text, but 
+  DESCRIPTION is more interesting.  It contains a line of text
+  followed by the C<=head2> subsection, METHODS.  This contains
+  a line of text and a list extending from the C<=over 4> to the 
+  final C<=back> just before the AUTHOR section starts.  The list
+  contains 2 items, C<new(\%config)>, which itself contains some 
+  text and a list of 2 items, and C<print()>.
+  
+  Presented as plain text and using indentation to indicate the element 
+  nesting, the model then looks something like this :

+  
+  Notice how we can make certain assumptions about various elements.
+  For example, we can assume that any C<=head1> section we find begins a
+  new section and implicitly ends any previous section.  Similarly, we
+  can assume an C<=item> ends when the next one begins, and so on.  In
+  terms of the XML example shown above, we are saying that we're smart
+  enough to add a C<E<lt>/head1E<gt>> element to terminate any
+  previously opened C<E<lt>head1E<gt>> when we find a new C<=head1> tag
+  in the input document.
+  
+  However you like to visualise the content, it all comes down to the
+  same underlying model.  The job of the Pod::POM module is to read an
+  input Pod document and build an object model to represent it in this
+  structured form. 
+  
+  Each node in the tree (i.e. element in the document) is represented
+  by a Pod::POM::Node::* object.  These encapsulate the attributes for
+  an element (such as the title for a C<=head1> tag) and also act as
+  containers for further Pod::POM::Node::* objects representing the
+  content of the element.  Right down at the leaf nodes, we have simple
+  object types to represent formatted and verbatim text paragraphs and
+  other basic elements like these.
+  
+  =head2 Parsing Pod
+  
+  The Pod::POM module implements the methods parse_file($file),
+  parse_text($text) and parse($file_or_text) to parse Pod files and
+  input text.  They return a Pod::POM::Node::Pod object to represent the
+  root of the Pod Object Model, effectively the C<E<lt>podE<gt>> element
+  in the XML tree shown above.
+  
+      use Pod::POM;
+  
+      my $parser = Pod::POM->new();
+      my $pom = $parser->parse_file($filename)
+          || die $parser->error();
+  
+  The parse(), parse_text() and parse_file() methods return
+  undef on error.  The error() method can be called to retrieve the
+  error message generated.  Parsing a document may also generate
+  non-fatal warnings.  These can be retrieved via the warnings() method
+  which returns a reference to a list when called in scalar context or a
+  list of warnings when called in list context.
+  
+      foreach my $warn ($parser->warnings()) {
+  	warn $warn, "\n";
+      }
+  
+  Alternatively, the 'warn' configuration option can be set to have
+  warnings automatically raised via C<warn()> as they are encountered.
+  
+      my $parser = Pod::POM->new( warn => 1 );
+  
+  =head2 Walking the Object Model
+  
+  Having parsed a document into an object model, we can then select 
+  various items from it.  Each node implements methods (via AUTOLOAD)
+  which correspond to the attributes and content elements permitted
+  within in.
+  
+  So to fetch the list of '=head1' sections within our parsed document,
+  we would do the following:
+  
+      my $sections = $pom->head1();
+  
+  Methods like this will return a list of further Pod::POM::Node::* 
+  objects when called in list context or a reference to a list when 
+  called in scalar context.  In the latter case, the list is blessed
+  into the Pod::POM::Node::Content class which gives it certain 
+  magical properties (more on that later).
+  
+  Given the list of Pod::POM::Node::Head1 objects returned by the above,
+  we can print the title attributes of each like this:
+  
+      foreach my $s (@$sections) {
+  	print $s->title();
+      }
+  
+  Let's look at the second section, DESCRIPTION.
+  
+      my $desc = $sections->[1];
+  
+  We can print the title of each subsection within it:
+  
+      foreach my $ss ($desc->head2()) {
+  	print $ss->title();
+      }
+  
+  Hopefully you're getting the idea by now, so here's a more studly
+  example to print the title for each item contained in the first list
+  within the METHODS section:
+  
+      foreach my $item ($desc->head2->[0]->over->[0]->item) {
+  	print $item->title(), "\n";
+      }
+  
+  =head2 Element Content
+  
+  This is all well and good if you know the precise structure of a 
+  document in advance.  For those more common cases when you don't,
+  each node that can contain other nodes provides a 'content' method
+  to return a complete list of all the other nodes that it contains.
+  The 'type' method can be called on any node to return its element
+  type (e.g. 'head1', 'head2', 'over', item', etc).
+  
+      foreach my $item ($pom->content()) {
+  	my $type = $item->type();
+  	if ($type eq 'head1') {
+  	    ...
+  	}
+  	elsif ($type eq 'head2') {
+  	    ...
+  	}
+  	...
+      }
+  
+  The content for an element is represented by a reference to a list,
+  blessed into the Pod::POM::Node::Content class.  This provides some
+  magic in the form of an overloaded stringification operator which 
+  will automatically print the contents of the list if you print 
+  the object itself.  In plain English, or rather, in plain Perl,
+  this means you can do things like the following:
+  
+      foreach my $head1 ($pom->head1()) {
+  	print '<h1>', $head1->title(), "</h1>\n\n";
+  	print $head1->content();
+      }
+  
+      # print all the root content
+      foreach my $item ($pom->content()) {
+  	print $item;
+      }
+  
+      # same as above
+      print $pom->content();
+  
+  In fact, all Pod::POM::Node::* objects provide this same magic, and
+  will attempt to Do The Right Thing to present themselves in the
+  appropriate manner when printed.  Thus, the following are all valid.
+  
+      print $pom;			# entire document
+      print $pom->content;	# content of document
+      print $pom->head1->[0];	# just first section
+      print $pom->head1;		# print all sections
+      foreach my $h1 ($pom->head1()) {
+  	print $h1->head2();	# print all subsections
+      }
+  
+  =head2 Output Views
+  
+  To understand how the different elements go about presenting
+  themselves in "the appropriate manner", we must introduce the concept
+  of a view.  A view is quite simply a particular way of looking at the
+  model.  In real terms, we can think of a view as being some kind of
+  output type generated by a pod2whatever converter.  Notionally we can
+  think in terms of reading in an input document, building a Pod Object
+  Model, and then generating an HTML view of the document, and/or a
+  LaTeX view, a plain text view, and so on.
+  
+  A view is represented in this case by an object class which contains
+  methods for displaying each of the different element types that could
+  be encountered in any Pod document.  There's a method for displaying
+  C<=head1> sections (view_head1()), another method for displaying
+  C<=head2> sections (view_head2()), one for C<=over> (view_over()),
+  another for C<=item> (view_item()) and so on.
+  
+  If we happen to have a reference to a $node and we know it's a 'head1'
+  node, then we can directly call the right view method to have it
+  displayed properly:
+  
+      $view = 'Pod::POM::View::HTML';
+      $view->view_head1($node);
+  
+  Thus our earlier example can be modified to be I<slightly> less laborious
+  and I<marginally> more flexible.
+  
+      foreach my $node ($pom->content) {
+  	my $type = $node->type();
+  	if ($type eq 'head1') {
+  	    print $view->view_head1($node);
+  	}
+  	elsif ($type eq 'head2') {
+  	    print $view->view_head2($node);
+  	}
+  	...
+      }
+  
+  However, this is still far from ideal.  To make life easier, each
+  Pod::POM::Node::* class inherits (or possibly redefines) a
+  C<present($view)> method from the Pod::POM::Node base class.  This method
+  expects a reference to a view object passed as an argument, and it
+  simply calls the appropriate view_xxx() method on the view object,
+  passing itself back as an argument.  In object parlance, this is known
+  as "double dispatch".  The beauty of it is that you don't need to know
+  what kind of node you have to be able to print it.  You simply pass
+  it a view object and leave it to work out the rest.
+  
+      foreach my $node ($pom->content) {
+  	print $node->present($view);
+      }
+  
+  If $node is a Pod::POM::Node::Head1 object, then the view_head1($node)
+  method gets called against the $view object.  Otherwise, if it's a
+  Pod::POM::Node::Head2 object, then the view_head2($node) method is
+  dispatched.  And so on, and so on, with each node knowing what it is
+  and where it's going as if determined by some genetically pre-programmed
+  instinct.  Fullfilling their destinies, so to speak.
+  
+  Double dispatch allows us to do away with all the explicit type
+  checking and other nonsense and have the node objects themselves worry
+  about where they should be routed to.  At the cost of an extra method
+  call per node, we get programmer convenience, and that's usually 
+  a Good Thing.
+  
+  Let's have a look at how the view and node classes might be
+  implemented.
+  
+      package Pod::POM::View::HTML;
+  
+      sub view_pod {
+  	my ($self, $node) = @_;
+  	return $node->content->present($self);
+      }
+  
+      sub view_head1 {
+  	my ($self, $node) = @_;
+  	return "<h1>", $node->title->present($self), "</h1>\n\n"
+  	     . $node->content->present($self);
+      }
+  
+      sub view_head2 {
+  	my ($self, $node) = @_;
+  	return "<h2>", $node->title->present($self), "</h2>\n\n"
+  	     . $node->content->present($self);
+      }
+  
+      ...
+  
+      package Pod::POM::Node::Pod;
+  
+      sub present {
+  	my ($self, $view) = @_;
+  	$view->view_pod($self);
+      }
+  
+      package Pod::POM::Node::Head1;
+  
+      sub present {
+  	my ($self, $view) = @_;
+  	$view->view_head1($self);
+      }
+  
+      package Pod::POM::Node::Head2;
+  
+      sub present {
+  	my ($self, $view) = @_;
+  	$view->view_head2($self);
+      }
+  
+      ...
+  
+  Some of the view_xxx methods make calls back against the node objects
+  to display their attributes and/or content.  This is shown in, for
+  example, the view_head1() method above, where the method prints the
+  section title in C<E<lt>h1E<gt>>...C<E<lt>h1E<gt>> tags, followed by
+  the remaining section content.
+  
+  Note that the title() attribute is printed by calling its present()
+  method, passing on the reference to the current view.  Similarly,
+  the content present() method is called giving it a chance to Do
+  The Right Thing to present itself correctly via the view object.
+  
+  There's a good chance that the title attribute is going to be regular
+  text, so we might be tempted to simply print the title rather than 
+  call its present method.
+  
+      sub view_head1 {
+  	my ($self, $node) = @_;
+  	# not recommended, prefer $node->title->present($self)
+  	return "<h1>", $node->title(), "</h1>\n\n", ...
+      }
+  
+  However, it is entirely valid for titles and other element attributes,
+  as well as regular, formatted text blocks to contain code sequences,
+  such like C<BE<lt>thisE<gt>> and C<IE<lt>thisE<gt>>.  These are used
+  to indicate different markup styles, mark external references or index
+  items, and so on.  What's more, they can be C<BE<lt>nested
+  IE<lt>indefinatelyE<gt>E<gt>>.  Pod::POM takes care of all this by
+  parsing such text, along with any embedded sequences, into Yet Another
+  Tree, the root node of which is a Pod::POM::Node::Text object,
+  possibly containing other Pod::POM::Node::Sequence objects.  When the
+  text is presented, the tree is automatically walked and relevant
+  callbacks made against the view for the different sequence types.  The
+  methods called against the view are all prefixed 'view_seq_', e.g.
+  'view_seq_bold', 'view_seq_italic'.
+  
+  Now the real magic comes into effect.  You can define one view to
+  render bold/italic text in one style:
+  
+      package My::View::Text;
+      use base qw( Pod::POM::View::Text );
+  
+      sub view_seq_bold {
+  	my ($self, $text) = @_;
+  	return "*$text*";
+      }
+  
+      sub view_seq_italic {
+  	my ($self, $text) = @_;
+  	return "_$text_";
+      }
+  
+  And another view to render it in a different style:
+  
+      package My::View::HTML;
+      use base qw( Pod::POM::View::HTML );
+  
+      sub view_seq_bold {
+  	my ($self, $text) = @_;
+  	return "<b>$text</b>";
+      }
+  
+      sub view_seq_italic {
+  	my ($self, $text) = @_;
+  	return "<i>$text</i>";
+      }
+  
+  Then, you can easily view a Pod Object Model in either style:
+  
+      my $text = 'My::View::Text';
+      my $html = 'My::View::HTML';
+  
+      print $pom->present($text);
+      print $pom->present($html);
+  
+  And you can apply this technique to any node within the object
+  model.
+  
+      print $pom->head1->[0]->present($text);
+      print $pom->head1->[0]->present($html);
+  
+  In these examples, the view passed to the present() method has 
+  been a class name.  Thus, the view_xxx methods get called as 
+  class methods, as if written:
+  
+      My::View::Text->view_head1(...);
+  
+  If your view needs to maintain state then you can create a view object
+  and pass that to the present() method.  
+  
+      my $view = My::View->new();
+      $node->present($view);
+  
+  In this case the view_xxx methods get called as object methods.
+  
+      sub view_head1 {
+  	my ($self, $node) = @_;
+  	my $title = $node->title();
+  	if ($title eq 'NAME' && ref $self) {
+  	    $self->{ title } = $title();
+  	}
+  	$self->SUPER::view_head1($node);
+      }
+  
+  Whenever you print a Pod::POM::Node::* object, or do anything to cause
+  Perl to stringify it (such as including it another quoted string "like
+  $this"), then its present() method is automatically called.  When
+  called without a view argument, the present() method uses the default
+  view specified in $Pod::POM::DEFAULT_VIEW, which is, by default,
+  'Pod::POM::View::Pod'.  This view regenerates the original Pod
+  document, although it should be noted that the output generated may
+  not be exactly the same as the input.  The parser is smart enough to
+  detect some common errors (e.g. not terminating an C<=over> with a C<=back>)
+  and correct them automatically.  Thus you might find a C<=back>
+  correctly placed in the output, even if you forgot to add it to the 
+  input.  Such corrections raise non-fatal warnings which can later
+  be examined via the warnings() method.
+  
+  You can update the $Pod::POM::DEFAULT_VIEW package variable to set the 
+  default view, or call the default_view() method.  The default_view() 
+  method will automatically load any package you specify.  If setting
+  the package variable directly, you should ensure that any packages
+  required have been pre-loaded.
+  
+      use My::View::HTML;
+      $Pod::POM::DEFAULT_VIEW = 'My::View::HTML';
+  
+  or
+  
+      Pod::POM->default_view('My::View::HTML');
+  
+  =head2 Template Toolkit Views
+  
+  One of the motivations for writing this module was to make it easier
+  to customise Pod documentation to your own look and feel or local
+  formatting conventions.  By clearly separating the content
+  (represented by the Pod Object Model) from the presentation style
+  (represented by one or more views) it becomes much easier to achieve
+  this.
+  
+  The latest version of the Template Toolkit (2.06 at the time of
+  writing) provides a Pod plugin to interface to this module.  It also
+  implements a new (but experimental) VIEW directive which can be used
+  to build different presentation styles for converting Pod to other
+  formats.  The Template Toolkit is available from CPAN:
+  
+      http://www.cpan.org/modules/by-module/Template/
+  
+  Template Toolkit views are similar to the Pod::POM::View objects
+  described above, except that they allow the presentation style for
+  each Pod component to be written as a template file or block rather
+  than an object method.  The precise syntax and structure of the VIEW
+  directive is subject to change (given that it's still experimental),
+  but at present it can be used to define a view something like this:
+  
+      [% VIEW myview %]
+  
+         [% BLOCK view_head1 %]
+            <h1>[% item.title.present(view) %]</h1>
+            [% item.content.present(view) %]
+         [% END %]
+   
+         [% BLOCK view_head2 %]
+            <h2>[% item.title.present(view) %]</h2>
+            [% item.content.present(view) %]
+         [% END %]
+  
+         ...
+  
+      [% END %]
+  
+  A plugin is provided to interface to the Pod::POM module:
+  
+      [% USE pod %]
+      [% pom = pod.parse('/path/to/podfile') %]
+  
+  The returned Pod Object Model instance can then be navigated and
+  presented via the view in almost any way imaginable:
+  
+      <h1>Table of Contents</h1>
+      <ul>
+      [% FOREACH section = pom.head1 %]
+         <li>[% section.title.present(view) %]
+      [% END %]
+      </ul>
+  
+      <hr>
+  
+      [% FOREACH section = pom.head1 %]
+         [% section.present(myview) %]
+      [% END %]
+  
+  You can either pass a reference to the VIEW (myview) to the 
+  present() method of a Pod::POM node:
+  
+      [% pom.present(myview) %]	    # present entire document
+  
+  Or alternately call the print() method on the VIEW, passing the 
+  Pod::POM node as an argument:
+  
+      [% myview.print(pom) %]
+  
+  Internally, the view calls the present() method on the node,
+  passing itself as an argument.  Thus it is equivalent to the 
+  previous example.
+  
+  The Pod::POM node and the view conspire to "Do The Right Thing" to 
+  process the right template block for the node.  A reference to the
+  node is available within the template as the 'item' variable.
+  
+     [% BLOCK view_head2 %]
+        <h2>[% item.title.present(view) %]</h2>
+        [% item.content.present(view) %]
+     [% END %]
+  
+  The Template Toolkit documentation contains further information on
+  defining and using views.  However, as noted above, this may be
+  subject to change or incomplete pending further development of the 
+  VIEW directive.
+  
+  =head1 METHODS
+  
+  =head2 new(\%config)
+  
+  Constructor method which instantiates and returns a new Pod::POM 
+  parser object.  
+  
+      use Pod::POM;
+  
+      my $parser = Pod::POM->new();
+  
+  A reference to a hash array of configuration options may be passed as
+  an argument.
+  
+      my $parser = Pod::POM->new( { warn => 1 } );
+  
+  For convenience, configuration options can also be passed as a list of
+  (key =E<gt> value) pairs.
+  
+      my $parser = Pod::POM->new( warn => 1 );
+  
+  The following configuration options are defined:
+  
+  =over 4
+  
+  =item code
+  
+  This option can be set to have all non-Pod parts of the input document
+  stored within the object model as 'code' elements, represented by 
+  objects of the Pod::POM::Node::Code class.  It is disabled by default
+  and code sections are ignored.  
+  
+      my $parser = Pod::POM->new( code => 1 );
+      my $podpom = $parser->parse(\*DATA);
+  
+      foreach my $code ($podpom->code()) {
+  	print "<pre>$code</pre>\n";
+      }
+  
+      __DATA__
+      This is some program code.
+  
+      =head1 NAME
+  
+      ...
+  
+  This will generate the output:
+  
+      <pre>This is some program code.</pre>
+  
+  Note that code elements are stored within the POM element in which
+  they are encountered.  For example, the code element below embedded
+  within between Pod sections is stored in the array which can be
+  retrieved by calling C<$podpom-E<gt>head1-E<gt>[0]-E<gt>code()>.
+  
+      =head1 NAME
+  
+      My::Module::Name;
+  
+      =cut
+  
+      Some program code embedded in Pod.
+  
+      =head1 SYNOPSIS
+  
+      ...
+  
+  =item warn
+  
+  Non-fatal warnings encountered while parsing a Pod document are stored 
+  internally and subsequently available via the warnings() method.
+  
+      my $parser = Pod::POM->new();
+      my $podpom = $parser->parse_file($filename);
+  
+      foreach my $warning ($parser->warnings()) {
+  	warn $warning, "\n";
+      }
+  
+  The 'warn' option can be set to have warnings raised automatically 
+  via C<warn()> as and when they are encountered.
+  
+      my $parser = Pod::POM->new( warn => 1 );
+      my $podpom = $parser->parse_file($filename);
+  
+  If the configuration value is specified as a subroutine reference then
+  the code will be called each time a warning is raised, passing the
+  warning message as an argument.
+  
+      sub my_warning {
+  	my $msg = shift;
+  	warn $msg, "\n";
+      };
+  
+      my $parser = Pod::POM->new( warn => \&my_warning );
+      my $podpom = $parser->parse_file($filename);
+  
+  =item meta
+  
+  The 'meta' option can be set to allow C<=meta> tags within the Pod
+  document.  
+  
+      my $parser = Pod::POM->new( meta => 1 );
+      my $podpom = $parser->parse_file($filename);
+  
+  This is an experimental feature which is not part of standard
+  POD.  For example:
+  
+      =meta author Andy Wardley
+  
+  These are made available as metadata items within the root
+  node of the parsed POM.
+  
+      my $author = $podpom->metadata('author');
+  
+  See the L<METADATA|METADATA> section below for further information.
+  
+  =back
+  
+  =head2 parse_file($file)
+  
+  Parses the file specified by name or reference to a file handle.
+  Returns a reference to a Pod::POM::Node::Pod object which represents
+  the root node of the Pod Object Model on success.  On error, undef
+  is returned and the error message generated can be retrieved by calling
+  error().
+  
+      my $podpom = $parser->parse_file($filename)
+          || die $parser->error();
+  
+      my $podpom = $parser->parse_file(\*STDIN)
+          || die $parser->error();
+  
+  Any warnings encountered can be examined by calling the 
+  warnings() method.
+  
+      foreach my $warn ($parser->warnings()) {
+  	warn $warn, "\n";
+      }
+  
+  =head2 parse_text($text)
+  
+  Parses the Pod text string passed as an argument into a Pod Object
+  Model, as per parse_file().
+  
+  =head2 parse($text_or_$file)
+  
+  General purpose method which attempts to Do The Right Thing in calling
+  parse_file() or parse_text() according to the argument passed.  
+  
+  A hash reference can be passed as an argument that contains a 'text'
+  or 'file' key and corresponding value. 
+  
+      my $podpom = $parser->parse({ file => $filename })
+          || die $parser->error();
+  
+  Otherwise, the argument can be a reference to an input handle which is
+  passed off to parse_file().  
+  
+      my $podpom = $parser->parse(\*DATA)
+          || die $parser->error();
+  
+  If the argument is a text string that looks like Pod text (i.e. it
+  contains '=' at the start of any line) then it is passed to parse_text().
+  
+      my $podpom = $parser->parse($podtext)
+          || die $parser->error();
+  
+  Otherwise it is assumed to be a filename and is passed to parse_file().
+  
+      my $podpom = $parser->parse($podfile)
+          || die $parser->error();
+  
+  =head1 NODE TYPES, ATTRIBUTES AND ELEMENTS
+  
+  This section lists the different nodes that may be present in a Pod Object
+  Model.  These are implemented as Pod::POM::Node::* object instances 
+  (e.g. head1 =E<gt> Pod::POM::Node::Head1).  To present a node, a view should
+  implement a method which corresponds to the node name prefixed by 'view_'
+  (e.g. head1 =E<gt> view_head1()).
+  
+  =over 4
+  
+  =item pod
+  
+  The C<pod> node is used to represent the root node of the Pod Object Model.
+  
+  Content elements: head1, head2, head3, head4, over, begin, for,
+  verbatim, text, code.
+  
+  =item head1
+  
+  A C<head1> node contains the Pod content from a C<=head1> tag up to the 
+  next C<=head1> tag or the end of the file.
+  
+  Attributes: title
+  
+  Content elements: head2, head3, head4, over, begin, for, verbatim, text, code.
+  
+  =item head2
+  
+  A C<head2> node contains the Pod content from a C<=head2> tag up to the 
+  next C<=head1> or C<=head2> tag or the end of the file.
+  
+  Attributes: title
+  
+  Content elements: head3, head4, over, begin, for, verbatim, text, code.
+  
+  =item head3
+  
+  A C<head3> node contains the Pod content from a C<=head3> tag up to the 
+  next C<=head1>, C<=head2> or C<=head3> tag or the end of the file.
+  
+  Attributes: title
+  
+  Content elements: head4, over, begin, for, verbatim, text, code.
+  
+  =item head4
+  
+  A C<head4> node contains the Pod content from a C<=head4> tag up to the 
+  next C<=head1>, C<=head2>, C<=head3> or C<=head4> tag or the end of the file.
+  
+  Attributes: title
+  
+  Content elements: over, begin, for, verbatim, text, code.
+  
+  =item over
+  
+  The C<over> node encloses the Pod content in a list starting at an C<=over> 
+  tag and continuing up to the matching C<=back> tag.  Lists may be nested 
+  indefinately.
+  
+  Attributes: indent (default: 4)
+  
+  Content elements: over, item, begin, for, verbatim, text, code.
+  
+  =item item
+  
+  The C<item> node encloses the Pod content in a list item starting at an 
+  C<=item> tag and continuing up to the next C<=item> tag or a C<=back> tag
+  which terminates the list.
+  
+  Attributes: title (default: *)
+  
+  Content elements: over, begin, for, verbatim, text, code.
+  
+  =item begin
+  
+  A C<begin> node encloses the Pod content in a conditional block starting 
+  with a C<=begin> tag and continuing up to the next C<=end> tag.
+  
+  Attributes: format
+  
+  Content elements: verbatim, text, code.
+  
+  =item for
+  
+  A C<for> node contains a single paragraph containing text relevant to a 
+  particular format.
+  
+  Attributes: format, text
+  
+  =item verbatim
+  
+  A C<verbatim> node contains a verbatim text paragraph which is prefixed by
+  whitespace in the source Pod document (i.e. indented).
+  
+  Attributes: text
+  
+  =item text
+  
+  A C<text> node contains a regular text paragraph.  This may include 
+  embedded inline sequences.
+  
+  Attributes: text
+  
+  =item code
+  
+  A C<code> node contains Perl code which is by default, not considered to be 
+  part of a Pod document.  The C<code> configuration option must be set for
+  Pod::POM to generate code blocks, otherwise they are ignored.
+  
+  Attributes: text
+  
+  =back
+  
+  =head1 INLINE SEQUENCES
+  
+  Embedded sequences are permitted within regular text blocks (i.e. not
+  verbatim) and title attributes.  To present these sequences, a view
+  should implement methods corresponding to the sequence name, prefixed
+  by 'view_seq_' (e.g. bold =E<gt> view_seq_bold()).
+  
+  =over 4
+  
+  =item code
+  
+  Code extract, e.g. CE<lt>my codeE<gt>
+  
+  =item bold
+  
+  Bold text, e.g. BE<lt>bold textE<gt>
+  
+  =item italic
+  
+  Italic text, e.g. IE<lt>italic textE<gt>
+  
+  =item link
+  
+  A link (cross reference), e.g. LE<lt>My::ModuleE<gt>
+  
+  =item space
+  
+  Text contains non-breaking space, e.g.SE<lt>Buffy The Vampire SlayerE<gt>
+  
+  =item file

+  
+  =item index
+

+  
+  =item zero
+  
+  A zero-width character, e.g. ZE<lt>E<gt>
+  
+  =item entity
+  
+  An entity escape, e.g. EE<lt>ltE<gt>
+  
+  =back
+  
+  =head1 BUNDLED MODULES AND TOOLS
+  
+  The Pod::POM module distribution includes a number of sample view
+  objects for rendering Pod Object Models into particular formats.  These
+  are incomplete and may require some further work, but serve at present to 
+  illustrate the principal and can be used as the basis for your own view
+  objects.
+  
+  =over 4
+  
+  =item Pod::POM::View::Pod
+  
+  Regenerates the model as Pod.
+  
+  =item Pod::POM::View::Text
+  
+  Presents the model as plain text.
+  
+  =item Pod::POM::View::HTML
+  
+  Presents the model as HTML.
+  
+  =back
+  
+  A script is provided for converting Pod documents to other format by
+  using the view objects provided.  The C<pom2> script should be called 
+  with two arguments, the first specifying the output format, the second
+  the input filename.  e.g.
+  
+      $ pom2 text My/Module.pm > README
+      $ pom2 html My/Module.pm > ~/public_html/My/Module.html
+  
+  You can also create symbolic links to the script if you prefer and 
+  leave it to determine the output format from its own name.
+  
+      $ ln -s pom2 pom2text	
+      $ ln -s pom2 pom2html
+      $ pom2text My/Module.pm > README
+      $ pom2html My/Module.pm > ~/public_html/My/Module.html
+  
+  The distribution also contains a trivial script, C<podlint>
+  (previously C<pomcheck>), which checks a Pod document for
+  well-formedness by simply parsing it into a Pod Object Model with
+  warnings enabled.  Warnings are printed to STDERR.
+  
+      $ podlint My/Module.pm
+  
+  The C<-f> option can be set to have the script attempt to fix any problems
+  it encounters.  The regenerated Pod output is printed to STDOUT.
+  
+      $ podlint -f My/Module.pm > newfile
+  
+  =head1 METADATA
+  
+  This module includes support for an experimental new C<=meta> tag.  This
+  is disabled by default but can be enabled by loading Pod::POM with the 
+  C<meta> option.
+  
+      use Pod::POM qw( meta );
+  
+  Alternately, you can specify the C<meta> option to be any true value when 
+  you instantiate a Pod::POM parser:
+  
+      my $parser = Pod::POM->new( meta => 1 );
+      my $pom    = $parser->parse_file($filename);
+  
+  Any C<=meta> tags in the document will be stored as metadata items in the 
+  root node of the Pod model created.  
+  
+  For example:
+  
+      =meta module Foo::Bar
+  
+      =meta author Andy Wardley
+  
+  You can then access these items via the metadata() method.
+  
+      print "module: ", $pom->metadata('module'), "\n";
+      print "author: ", $pom->metadata('author'), "\n";
+  
+  or
+  
+      my $metadata = $pom->metadata();
+      print "module: $metadata->{ module }\n";
+      print "author: $metadata->{ author }\n";
+  
+  Please note that this is an experimental feature which is not supported by
+  other POD processors and is therefore likely to be most incompatible.  Use
+  carefully.

+      ...
+  
+  =head1 DESCRIPTION
+  
+  This documentation describes the inner workings of the Pod::POM::Node
+  module and gives a brief overview of the relationship between it and
+  its derived classes.  It is intended more as a guide to the internals
+  for interested hackers than as general user documentation.  See 
+  L<Pod::POM> for information on using the modules.
+  
+  This module implements a base class node which is subclassed to
+  represent different elements within a Pod Object Model. 
+  
+      package Pod::POM::Node::Over;
+      use base qw( Pod::POM::Node );
+  
+  The base class implements the new() constructor method to instantiate 
+  new node objects.  
+  
+      my $list = Pod::POM::Node::Over->new();
+  
+  The characteristics of a node can be specified by defining certain
+  variables in the derived class package.  The C<%ATTRIBS> hash can be
+  used to denote attributes that the node should accept.  In the case of
+  an C<=over> node, for example, an C<indent> attribute can be specified
+  which otherwise defaults to 4.
+  
+      package Pod::POM::Node::Over;
+      use base qw( Pod::POM::Node );
+      use vars qw( %ATTRIBS $ERROR );
+  
+      %ATTRIBS = ( indent => 4 );
+  
+  The new() method will now expect an argument to set the indent value, 
+  or will use 4 as the default if no argument is provided.
+  
+      my $list = Pod::POM::Node::Over->new(8);	# indent: 8
+      my $list = Pod::POM::Node::Over->new( );	# indent: 4
+  
+  If the default value is undefined then the argument is mandatory.
+  
+      package Pod::POM::Node::Head1;
+      use base qw( Pod::POM::Node );
+      use vars qw( %ATTRIBS $ERROR );
+  
+      %ATTRIBS = ( title => undef );
+  
+      package main;
+      my $head = Pod::POM::Node::Head1->new('My Title');
+  
+  If a mandatory argument isn't provided then the constructor will
+  return undef to indicate failure.  The $ERROR variable in the derived
+  class package is set to contain a string of the form "$type expected a
+  $attribute".
+  
+      # dies with error: "head1 expected a title"
+      my $head = Pod::POM::Node::Head1->new()
+  	|| die $Pod::POM::Node::Head1::ERROR;
+  
+  For convenience, the error() subroutine can be called as a class
+  method to retrieve this value.
+  
+      my $type = 'Pod::POM::Node::Head1';
+      my $head = $type->new()
+  	|| die $type->error();
+  
+  The C<@ACCEPT> package variable can be used to indicate the node types
+  that are permitted as children of a node.
+  
+      package Pod::POM::Node::Head1;
+      use base qw( Pod::POM::Node );
+      use vars qw( %ATTRIBS @ACCEPT $ERROR );
+  
+      %ATTRIBS =   ( title => undef );
+      @ACCEPT  = qw( head2 over begin for text verbatim );
+  
+  The add() method can then be called against a node to add a new child
+  node as part of its content.
+  
+      $head->add('over', 8);
+  
+  The first argument indicates the node type.  The C<@ACCEPT> list is
+  examined to ensure that the child node type is acceptable for the
+  parent node.  If valid, the constructor for the relevant child node
+  class is called passing any remaining arguments as attributes.  The 
+  new node is then returned.
+  
+      my $list = $head->add('over', 8);
+  
+  The error() method can be called against the I<parent> node to retrieve
+  any constructor error generated by the I<child> node.
+  
+      my $list = $head->add('over', 8);
+      die $head->error() unless defined $list;
+  
+  If the child node is not acceptable to the parent then the add()
+  method returns one of the constants IGNORE, REDUCE or REJECT, as
+  defined in Pod::POM::Constants.  These return values are used by the
+  Pod::POM parser module to implement a simple shift/reduce parser.  
+  
+  In the most common case, IGNORE is returned to indicate that the
+  parent node doesn't know anything about the new child node.  The 
+  parser uses this as an indication that it should back up through the
+  parse stack until it finds a node which I<will> accept this child node.
+  Through this mechanism, the parser is able to implicitly terminate
+  certain POD blocks.  For example, a list item initiated by a C<=item>
+  tag will I<not> accept another C<=item> tag, but will instead return IGNORE.
+  The parser will back out until it finds the enclosing C<=over> node 
+  which I<will> accept it.  Thus, a new C<=item> implicitly terminates any
+  previous C<=item>.
+  
+  The C<$EXPECT> package variable can be used to indicate a node type
+  which a parent expects to terminate itself.  An C<=over> node, for 
+  example, should always be terminated by a matching C<=back>.  When 
+  such a match is made, the add() method returns REDUCE to indicate 
+  successful termination.
+  
+      package Pod::POM::Node::Over;
+      use base qw( Pod::POM::Node );
+      use vars qw( %ATTRIBS @ACCEPT $EXPECT $ERROR );
+  
+      %ATTRIBS =   ( indent => 4 );
+      @ACCEPT  = qw( over item begin for text verbatim );
+      $EXPECT  =  q( back );
+  
+      package main;
+      my $list = Pod::POM::Node::Over->new();
+      my $item = $list->add('item');
+      $list->add('back');			# returns REDUCE
+  
+  If a child node isn't specified in the C<@ACCEPT> list or doesn't match 
+  any C<$EXPECT> specified then REJECT is returned.  The parent node sets
+  an internal error of the form "$type expected a terminating $expect".
+  The parser uses this to detect missing POD tags.  In nearly all cases
+  the parser is smart enough to fix the incorrect structure and downgrades
+  any errors to warnings.
+  
+      # dies with error 'over expected terminating back'
+      ref $list->add('head1', 'My Title')	    # returns REJECT
+          || die $list->error();
+  
+  Each node contains a 'type' field which contains a simple string
+  indicating the node type, e.g. 'head1', 'over', etc.  The $NODES and
+  $NAMES package variables (in the base class) reference hash arrays
+  which map these names to and from package names (e.g. head1 E<lt>=E<gt>
+  Pod::POM::Node::Head1).  
+  
+      print $list->{ type };	# 'over'
+  
+  An AUTOLOAD method is provided to access to such internal items for
+  those who don't like violating an object's encapsulation.
+  
+      print $list->type();
+  
+  Nodes also contain a 'content' list, blessed into the
+  Pod::POM::Node::Content class, which contains the content (child
+  elements) for the node.  The AUTOLOAD method returns this as a list
+  reference or as a list of items depending on the context in which it
+  is called.
+  
+      my $items = $list->content();
+      my @items = $list->content();
+  
+  Each node also contains a content list for each individual child node
+  type that it may accept.
+  
+      my @items = $list->item();
+      my @text  = $list->text();
+      my @vtext = $list->verbatim();
+  
+  The present() method is used to present a node through a particular view.
+  This simply maps the node type to a method which is then called against the 
+  view object.  This is known as 'double dispatch'.
+  
+      my $view = 'Pod::POM::View::HTML';
+      print $list->present($view);
+  
+  The method name is constructed from the node type prefixed by 'view_'.  
+  Thus the following are roughly equivalent.
+  
+      $list->present($view);
+  
+      $view->view_list($list);
+  
+  The benefit of the former over the latter is, of course, that the
+  caller doesn't need to know or determine the type of the node.  The 
+  node itself is in the best position to determine what type it is.

+  
+  =head1 SYNOPSIS
+  
+   use Pod::POM::View::Restructured;
+   
+   my $view = Pod::POM::View::Restructured->new;
+   my $parser = Pod::POM->new;

+  
+  
+  =head1 DESCRIPTION
+  
+  This module outputs reStructuredText that is expected to be used
+  with Sphinx.  Verbatim sections (indented paragraphs) in the POD
+  will be output with syntax hilighting for Perl code by default.
+  See L</"POD commands specifically for reStructuredText"> for how
+  to change this for a particular block.
+  
+  For a list of changes in recent versions, see the documentation
+  for L<Pod::POM::View::Restructured::Changes>.
+  
+  This module can be downloaded from L<http://www.cpan.org/authors/id/D/DO/DOWENS/>.

+  =head2 C<convert_file($source_file, $title, $dest_file, $callbacks)>
+  
+  Converts the POD in C<$source_file> to reStructuredText.  If
+  C<$dest_file> is defined, it writes the output there.  If
+  C<$title> is defined, it is used for the title of the document.
+  Otherwise, an attempt is made to infer the title from the NAME
+  section (checks if the body looks like C</\A\s*(\w+(?:::\w+)+)\s+-\s+/s>).
+  
+  Returns the output as a string.
+  
+  C<$source_file> and C<$dest_file> can be either file names or file
+  handles.

+  =head2 C<convert_files($file_spec, $index_file, $index_title, $out_dir)>
+  
+  Converts the files given in C<$file_spec> to reStructuredText.
+  If C<$index_file> is provided, it is the path to the index file
+  to be created (with a table of contents pointing to all of the
+  files created).  If C<$index_title> is provided, it is used as
+  the section title for the index file.  C<$out_dir> is the
+  directory the generated files will be written to.
+  
+  C<$file_spec> is a reference to an array of hashes specifying
+  attributes for each file to be converted.  The valid keys are:
+  
+  =over 4
+  
+  =item C<source_file>
+  
+  File to convert.
+  
+  =item C<dest_file>
+  
+  File to output the reStructuredText.  If not provided, a file
+  name will be generated based on the title.
+  
+  =item C<title>
+  
+  Section title for the generated reStructuredText.  If not
+  provided, an attempt will be made to infer the title from the
+  NAME section in the POD, if it exists.  As a last resort, a title
+  will be generated that looks like "section_(\d+)".
+  
+  =item C<callbacks>
+  
+  A reference to a hash containing names and the corresponding callbacks.
+  
+  Currently the only valid callback is C<link>.  It is given the
+  text inside a LE<lt>E<gt> section from the POD, and is expected to return a
+  tuple C<($url, $label)>.  If the value returned for C<$label> is
+  undefined, the value of C<$url> is used as the label.
+  
+  =item C<no_toc>
+  
+  Causes the item to not be printed to the index or return in the C<toc> field.
+  
+  =back
+

+  =head1 POD commands specifically for reStructuredText
+  
+  The following sequences can be used in POD to request actions specifically for this module.
+  
+  =head2 =Z<>for pod2rst next-code-block: I<lang>
+  
+  This sets up the next verbatim section, i.e., the next indented
+  paragraph to be hilighted according to the syntax of the
+  programming/markup/config language I<lang>.  Verbatim sections
+  are assumed to be Perl code by default.  Sphinx uses Pygments to
+  do syntax hilighting in these sections, so you can use any value
+  for I<lang> that Pygments supports, e.g., Python, C, C++,
+  Javascript, SQL, etc.

+  =head1 TODO
+  
+  =over 4
+  
+  =item code hilighting
+  
+  Currently, a verbatim block (indented paragraph) gets output as a
+  Perl code block by default in reStructuredText. There should be
+  an option (e.g., in the constructor) to change the language for
+  hilighting purposes (for all verbatim blocks), or disable syntax
+  hilighting and just make it a preformatted paragraph.  There is a
+  way to do this in POD (see L</"POD commands specifically for reStructuredText">),
+  but there should also be an option in the constructor.
+  
+  =item improve escaping
+  
+  Text blocks are not escaped properly, so it is currently possible
+  to invoke a command in reStructuredText by accident.
