1.3 harris41 22: # I am using a multiple pass-through approach to parsing
23: # the lpml file. This saves memory and makes sure the server
24: # will never be overloaded.
1.4 harris41 25: #
26: # This is meant to parse files meeting the lpml document type.
27: # See lpml.dtd. LPML=Linux Packaging Markup Language.

32: **** ERROR ERROR ERROR ERROR ****
33: Usage is for lpml file to come in through standard input.
34: 1st argument is the mode of parsing.
1.4 harris41 35: 2nd argument is the category permissions to use (runtime or development)
36: 3rd argument is the distribution (default,redhat6.2,debian2.2,redhat7.1,etc).
37: 4th argument is to manually specify a sourceroot.
38: 5th argument is to manually specify a targetroot.
1.3 harris41 39:
40: Only the 1st argument is mandatory for the program to run.
41:
42: Example:
43:
44: cat ../../doc/loncapafiles.lpml |\\
45: perl lpml_parse.pl html default /home/sherbert/loncapa /tmp/install
