	sbase -	Create class which will	provide	access to HTML files as	modules

	sbase $DOCUMENT_ROOT/..

       The first thing to never	ever forget about HTML::Seamstress is this:

	There is no magick *anywhere*

       If you know object-oriented Perl	and you	are comfortable	with
       conceptualizing HTML as a tree, then you	can never get confused.
       Everything that Seamstress offers is based on improving the synergy of
       these two powers.

       So, let's look at one way to manipulate HTML, completely	Seamstress-

	use HTML::TreeBuilder;
	my $tree = HTML::TreeBuilder->new_from_file('/usr/www/file.html');

       Let's make it easier to find "file.html":

	package	www::file;
	use base qw(HTML::Seamstress);

	sub new	{

       So now our code is this:

	use www::file;
	my $tree = www::file->new;

       Same amount of code. It's just we dont have to manage pathnames.

       Now, Seamstress actually	does something a little	more flexible in the
       package it creates for your class. Instead of a long absolute path, it
       abstracts away the root of the absolute path, creating a	class for your
       HTML file like this:

	package	www::file;
	use base qw(HTML::Seamstress::Base); # slight difference

	sub new	{
	      HTML::Seamstress::Base->comp_root() . 'file.html';

       And the mainline	code uses "www::file" just as before.

       So now we see some flexibility. The method
       "HTML::Seamstress::Base::comp_root()" can be configured to return
       values based on configuration settings and can vary based on deployment
       setup (e.g. production versus dev).

       So, sbase creates the "HTML::Seamstress::Base" package for you. It will
       work fine for most setups. If your root is not hardcoded	and must be
       derived by a series of function calls, then simply modify "" to
       fit your	setup. Where I work, our Base class looks like this:

	package	HTML::Seamstress::Base;
	use base qw(HTML::Seamstress);

	use Wigwam::Config;

	use vars     qw($comp_root);

	# put a	"/" on end of path - VERY important
	BEGIN	      {	$comp_root = $Wigwam::Config{'PLAYPEN_ROOT'} . '/' }

	use lib		$comp_root;

	sub comp_root {	$comp_root }


       "Wigwam"	is a tool for specifying all software and file path
       dependencies of your software: <>. So,
       we get our
