28: #
29: # I am using a multiple pass-through approach to parsing
30: # the lpml file. This saves memory and makes sure the server
31: # will never be overloaded.
32: #
33: # This is meant to parse files meeting the lpml document type.
34: # See lpml.dtd. LPML=Linux Packaging Markup Language.

39: **** ERROR ERROR ERROR ERROR ****
40: Usage is for lpml file to come in through standard input.
41: 1st argument is the mode of parsing.
42: 2nd argument is the category permissions to use (runtime or development)
43: 3rd argument is the distribution (default,redhat6.2,debian2.2,redhat7.1,etc).
44: 4th argument is to manually specify a sourceroot.
45: 5th argument is to manually specify a targetroot.
46:
47: Only the 1st argument is mandatory for the program to run.
48:
49: Example:
50:
51: cat ../../doc/loncapafiles.lpml |\\
52: perl lpml_parse.pl html default /home/sherbert/loncapa /tmp/install

1035: =head1 NAME
1036:
1037: lpml_parse.pl - This is meant to parse files meeting the lpml document type.
1038: See lpml.dtd. LPML=Linux Packaging Markup Language.
1039:
1040: =head1 SYNOPSIS
1041:
1042: Usage is for lpml file to come in through standard input.
1043:
1044: =over 4
1045:
1046: =item *
1047:
1048: 1st argument is the mode of parsing.
1049:
1050: =item *
1051:
1052: 2nd argument is the category permissions to use (runtime or development)
1053:
1054: =item *
1055:
1056: 3rd argument is the distribution
1057: (default,redhat6.2,debian2.2,redhat7.1,etc).
1058:
1059: =item *
1060:
1061: 4th argument is to manually specify a sourceroot.
1062:
1063: =item *
1064:
1065: 5th argument is to manually specify a targetroot.
1066:
1067: =back
1068:
1069: Only the 1st argument is mandatory for the program to run.
1070:
1071: Example:
1072:
1073: cat ../../doc/loncapafiles.lpml |\\
1074: perl lpml_parse.pl html default /home/sherbert/loncapa /tmp/install
1075:
1076: =head1 DESCRIPTION
1077:
1078: I am using a multiple pass-through approach to parsing
1079: the lpml file. This saves memory and makes sure the server
1080: will never be overloaded.
