1.3 harris41 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.
1.4 harris41 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.
1.4 harris41 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.
1.3 harris41 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
