=head1 DESCRIPTION	=head1 DESCRIPTION

I am using a multiple pass-through approach to parsing	The general flow of the script is to get command line arguments, run through
the lpml file. This saves memory and makes sure the server	the XML document three times, and output according to any desired mode:
will never be overloaded.	install, configinstall, build, rpm, dpkg, htmldoc, textdoc, and status.

	A number of coding decisions are made according to the following principle:
	installation software must be stand-alone. Therefore, for instance, I try
	not to use the GetOpt::Long module or any other perl modules. (I do however
	use HTML::TokeParser.) I also have tried to keep all the MODES of
	parsing inside this file. Therefore, format_TAG subroutines are fairly
	lengthy with their conditional logic. A more "elegant" solution might
	be to dynamically register the parsing mode and subroutines, or maybe even work
	with stylesheets. However, in order to make this the installation back-bone
	of choice, there are advantages for HAVING EVERYTHING IN ONE FILE.
	This way, the LPML installation software does not have to rely on OTHER
	installation software (a chicken versus the egg problem). Besides, I would
	suggest the modes of parsing are fairly constant: install, configinstall,
	build, rpm, dpkg, htmldoc, textdoc, and status.

	Another coding decision is about using a multiple pass-through approach to
	parsing the lpml file. This saves memory and makes sure the server will never
	be overloaded. During the first pass-through, the script gathers information
	specific as to resolving what tags with what 'dist=' attributes are to be used.
	During the second pass-through, the script cleans up white-space surrounding
	the XML tags, and filters through the tags based on information regarding the
	'dist=' attributes (information gathered in the first pass-through).
	The third and final pass-through involves formatting and rendering the XML
	into whatever XML mode is chosen: install, configinstall, build, rpm, dpkg,
	htmldoc, textdoc, and status.

	The hierarchy mandated by the DTD does not always correspond to the hierarchy
	that is sensible for a Makefile. For instance, in a Makefile it is sensible
	that soft-links are installed after files. However, in an LPML document, it
	is sensible that files and links be considered together and the writer of the
	LPML document should be free to place things in whatever order makes best
	sense in terms of LOOKING at the information. The complication that arises
	is that the parser needs to have a memory for passing values from
	leaves on the XML tree to higher-up branches. Currently, this memory is
	hard-coded (like with the @links array), but it may benefit from a more
	formal approach in the future.
