=head1 NAME

Pod::Simple::LinkSection -- represent "section" attributes of L codes

=head1 SYNOPSIS

 # a long story

=head1 DESCRIPTION

This class is not of interest to general users.

Pod::Simple uses this class for representing the value of the
"section" attribute of "L" start-element events.  Most applications
can just use the normal stringification of objects of this class;
they stringify to just the text content of the section,
such as "foo" for
C&lt;&lt; LZ&lt;&gt;&lt;Stuff/foo&gt; &gt;&gt;, and "bar" for 
C&lt;&lt; LZ&lt;&gt;&lt;Stuff/bIZ&lt;&gt;&lt;ar&gt;&gt; &gt;&gt;.

However, anyone particularly interested in getting the full value of
the treelet, can just traverse the content of the treeleet
@$treelet_object.  To wit:


  % perl -MData::Dumper -e
    "use base qw(Pod::Simple::Methody);
     sub start_L { print Dumper($_[1]{'section'} ) }
     __PACKAGE__-&gt;new-&gt;parse_string_document('=head1 L&lt;Foo/bI&lt;ar&gt;baz&gt;&gt;')
    "
Output:
  $VAR1 = bless( [
                   '',
                   {},
                   'b',
                   bless( [
                            'I',
                            {},
                            'ar'
                          ], 'Pod::Simple::LinkSection' ),
                   'baz'
                 ], 'Pod::Simple::LinkSection' );

But stringify it and you get just the text content:

  % perl -MData::Dumper -e
    "use base qw(Pod::Simple::Methody);
     sub start_L { print Dumper( '' . $_[1]{'section'} ) }
     __PACKAGE__-&gt;new-&gt;parse_string_document('=head1 L&lt;Foo/bI&lt;ar&gt;baz&gt;&gt;')
    "
Output:
  $VAR1 = 'barbaz';
