       Config::Pod - Configuration files in POD format

SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
        use Config::Pod;

        my $cfg = new Config::POD;

        $cfg -> filename($filename) or $cfg -> text($podtext);

        $cfg -> exists( @path )
        $cfg -> val( @path )

       Config::Pod allows configuration files to be written in
       POD.  Any text may be included at any location without
       affecting the configuration since Config::Pod only pays
       attention to lines beginning with `='.

       Headings must be properly nested (head1 followed by head3
       is not allowed, but head3 followed by head2 is allowed).

       The module searches for lines beginning with =_h_e_a_d(\d+)
       and =item.  Only items are leaf nodes and are stored in an
       array under the appropriate heading.

MMMMEEEETTTTHHHHOOOODDDDSSSS
       exists
       Given a list of keys, will return true if the list
       represents a (possibly empty) collection of leaf nodes
       (=items).  Note that intermediate headings will return
       false.

       filename
       If no arguments are present, returns the filename of the
       configuration source.  If an argument is given, it tries
       to read the file and parse the contents.

       keys
       Given a list of keys, will return an array (possibly
       empty) of keys which reside under the list.

       text
       Either an array or an array reference may be passed.  The
       contents will be parsed as a POD file.

       val
       Given a list of keys, will return an array reference
       (possibly empty) of items.

EEEEXXXXAAAAMMMMPPPPLLLLEEEE
       The following is an example POD file.

        =head1 Section1

        =head2 Section2

        =over 4

        =item Item1

        =item Item2

        =back 4

        =head2 Section3

        =head3 SectionA

        =over 4

        =item ItemA

        =item ItemB

        =back 4

        =head2 Section4

        =cut

       The following values then are available:

        $cfg -> val( qw(section1 section2) ) ==
           [ 'Item1', 'Item2' ];
        $cfg -> val( qw(section1 section3 sectiona) ) ==
           [ 'ItemA', 'ItemB' ];
        $cfg -> keys( qw(section1) ) ==
           ( qw(section2 section3 section4) );

       and

        $cfg -> exists( qw(section1 section4) );

       should return true even though it has no values.

       On the other hand,

        $cfg -> exists( qw(section1 section3) );

       should return false since there is yet another heading
       under Section3.
