Currently only has one function - mapping of packages to their dev/dbg/doc/locale etc.

functions on the pkgdata though.

Too lazy to use getopt

debug = False noopt = False args = [] for arg in sys.argv[1:]: if arg == "--": noopt = True else: if not noopt: if arg == "-d": debug = True continue args.append(arg)

if len(args) < 1: usage() sys.exit(1)

if args[0] == "glob": glob(args[1:]) else: usage() sys.exit(1)
