new pkg metadata generating scripts

Hi,
 I've been fixing up and getopting and other stuff the pkg metadata
generating scripts.

you can see them at:
http://linux.duke.edu/~skvidal/metadata/generate/

run genpkgmetadata.py with the other two in the include path. it has a
usage, etc.

one problem I'm having is that I'd like to write the xml out directly to
gzipped files but libxml2's saveTo() isn't outputting any data into
gzipOpen() returned file objects. Any cluebats appreciated.
