   =head1 NAME
   
   lpml_parse.pl - This is meant to parse files meeting the lpml document type.
   See lpml.dtd.  LPML=Linux Packaging Markup Language.
   
   =head1 SYNOPSIS
   
   Usage is for 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 default /home/sherbert/loncapa /tmp/install
   
   =head1 DESCRIPTION
   
   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.
