USAGE="\n\
This script is used to setup a git shared repo to clone an XBMC svn repo.\n\
Once setup, this script can also be used to continually fetch new revisions\n\
and can be used to push to another shared git repo.

 --perform-push             Performs a git push after fetching new svn revs.\n\
