   # 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.

 my $target = shift @ARGV;  my $usage=<<END;
 my $dist = shift @ARGV;  **** ERROR ERROR ERROR ERROR ****
   Usage is for lpml file to come in through standard input.
   1st argument is the mode of parsing.
   2nd argument is the category permissions to use (runtime or development)
   3rd argument is the distribution (default,redhat6.2,debian2.2,redhat7.1,etc).
   4th argument is to manually specify a sourceroot.
   5th argument is to manually specify a targetroot.
   
   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 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.
