   # ----------------------------------------------------------------------- Notes
   #
   # I am using a multiple pass-through approach to parsing
   # the lpml file.  This saves memory and makes sure the server
   # will never be overloaded.
   #
   # This is meant to parse files meeting the lpml document type.
   # See lpml.dtd.  LPML=Linux Packaging Markup Language.

 while (my $token = $p->get_tag("category")) {  my $usage=<<END;
     my $url = $token->[1]{name} . $token->[1]{type};  **** ERROR ERROR ERROR ERROR ****
     my $chmodtoken=$p->get_tag("chmod");  Usage is for lpml file to come in through standard input.
     my $text = $p->get_trimmed_text("/chmod");  1st argument is the mode of parsing:
     print "CHMOD: $text\n";      install,configinstall,build,rpm,dpkg,htmldoc,textdoc,status
     my $text = $p->get_trimmed_text("/category");  2nd argument is the category permissions to use:
     print "$url\t$text\t".join(" ",@{$token->[2]})."\n";      typical choices: runtime,development
   3rd argument is the distribution:
       typical choices: default,redhat6.2,debian2.2,redhat7
   4th argument is to manually specify a sourceroot.
   5th argument is to manually specify a targetroot.
   6th argument is to manually specify a shell.
   
   Only the 1st argument is mandatory for the program to run.
   
   Example:
   
   cat ../../doc/loncapafiles.lpml |\\
   perl lpml_parse.pl html development default /home/sherbert/loncapa /tmp/install

   =head1 NAME
   
   lpml_parse.pl - This is meant to parse files meeting the lpml document type.
   
   =head1 SYNOPSIS
   
   <STDIN> | perl lpml_parse.pl <MODE> <CATEGORY> <DIST> <SOURCE> <TARGET>
   
   Usage is for the lpml file to come in through standard input.
   
   =over 4
   
   =item *
   
   1st argument is the mode of parsing.
   
   =item * 
   
   2nd argument is the category permissions to use (runtime or development)
   
   =item *
   
   3rd argument is the distribution
   (default,redhat6.2,debian2.2,redhat7.1,etc).
   
   =item *
   
   4th argument is to manually specify a sourceroot.
   
   =item *
   
   5th argument is to manually specify a targetroot.
   
   =back
   
   Only the 1st argument is mandatory for the program to run.
   
   Example:
   
   cat ../../doc/loncapafiles.lpml |\\
   perl lpml_parse.pl html runtime default /home/sherbert/loncapa /tmp/install
   
   =head1 DESCRIPTION
   
   The general flow of the script is to get command line arguments, run through
   the XML document three times, and output according to any desired mode:
   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.
