NAME
       HTML::AsSubs - functions that construct a HTML syntax tree

VERSION
       This document describes version 5.03 of HTML::AsSubs, released September 22, 2012 as part
       of HTML-Tree.

SYNOPSIS
	use HTML::AsSubs;
	$h = body(
		  h1("This is the heading"),
		  p("This is the first paragraph which contains a ",
		    a({href=>'link.html'}, "link"),
		    " and an ",
		    img({src=>'img.gif', alt=>'image'}),
		    "."
		   ),
		 );
	print $h->as_HTML;

DESCRIPTION
       This module exports functions that can be used to construct various HTML elements. The
       functions are named after the tags of the corresponding HTML element and are all written
       in lower case. If the first argument is a hash reference then it will be used to
       initialize the attributes of this element. The remaining arguments are regarded as
       content.

       For a similar idea (i.e., it's another case where the syntax tree of the Perl source
       mirrors the syntax tree of the HTML produced), see HTML::Element's "new_from_lol" method.

       For what I now think is a cleaner implementation of this same idea, see the excellent
       module "XML::Generator", which is what I suggest for actual real-life use.  (I suggest
       this over "HTML::AsSubs" and over "CGI.pm"'s HTML-making functions.)

ACKNOWLEDGEMENT
       This module was inspired by the following message:

	Date: Tue, 4 Oct 1994 16:11:30 +0100
	Subject: Wow! I have a large lightbulb above my head!

	Take a moment to consider these lines:

	%OVERLOAD=( '""' => sub { join("", @{$_[0]}) } );

	sub html { my($type)=shift; bless ["<$type>", @_, "</$type>"]; }

	:-)  I *love* Perl 5!  Thankyou Larry and Ilya.

	Regards,
	Tim Bunce.

	p.s. If you didn't get it, think about recursive data types: html(html())
	p.p.s. I'll turn this into a much more practical example in a day or two.
	p.p.p.s. It's a pity that overloads are not inherited. Is this a bug?

BUGS
       The exported link() function overrides the builtin link() function.  The exported tr()
       function must be called using &tr(...) syntax because it clashes with the builtin
       tr/../../ operator.

       A bunch of methods for creating tags.

Private Functions
   _elem()
       The _elem() function is wrapped by all the html 'tag' functions. It takes a tag-name,
       optional hashref of attributes and a list of content as parameters.
