   # 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.
   
 use HTML::TokeParser;  use HTML::TokeParser;

 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";  2nd argument is the category permissions to use (runtime or development)
     my $text = $p->get_trimmed_text("/category");  3rd argument is the distribution (default,redhat6.2,debian2.2,redhat7.1,etc).
     print "$url\t$text\t".join(" ",@{$token->[2]})."\n";  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.
