Mediawiki::POD::HTML - a subclass to catch X keywords and =head lines

	use Mediawiki::POD::HTML;

	my $parser = Mediawiki::POD::HTML->new();

	my $html = $parser->parse_string_document($POD);

Turns a given POD (Plain Old Documentation) into HTML code.

This subclass of Pod::Simple::HTML catches =head directives, and then allows you to assemble a TOC (table of contents) from the captured headlines.

In addition, it supports graph-common and graph subsections, these will be turned into HTML graphs.

Mediawiki::POD::HTML allows you to write graphs (nodes connected with edges) in Graph::Easy or http://www.graphviz.org (Graphviz) format and turns these portions into HTML "graphics".

The following represents two graphs:

	=for graph [ Single ] --> [ Line ] --> [ Definition ]

	=begin graph

	node { fill: silver; }
	[ Mutli ] --> [ Line ]

	=end graph

In addition, a graph-common section can be used to set a common text for all following graphs. Each graph-common section resets the common text section:

	=for graph-common node { fill: red; }

	=for graph [ Red ]

	=for graph [ Red too ]

	=for graph-common node { fill: blue; }

	=for graph [ Blue ]

	=for graph [ Blue too ]

The attribute output for graphs is not yet used, eventually it should result in different output formats like SVG, or PNG rendered via dot.

Return all the captured headlines as an ARRAY ref.

	# Set external search engine to search for "Foo+Bar"
	$parser->keyword_search_url('http://search.cpan.org/perldoc?');

	# Generate URLs like "Foo_Bar", perfect for relative wiki links:
	$parser->keyword_search_url('', '_');

Get/set the URL that is used to link keywords defined with X<> to a search engine.

If the URL contains a text ##KEYWORD##, then this text will be replaced with the actual keyword. Otherwise, the keyword is simple appended to the URL.

The default search URL is:

  	http://cpan.uwinnipeg.ca/search?query=##KEYWORD##

Optionally set the character that replaces a space in generated URLs. The default space replacement character is undef, this means the character is dependend on the search URL:

* For URLS with ##KEYWORD##, it is '+'

* For URLS without a ##KEYWORD##, it is '_'
