Subject: util/gen_xmlpool: use argparse for argument handling
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2857b18991f86940af5759664a961a24d90e3a47;p=mesa.git

util/gen_xmlpool: use argparse for argument handling

This is a little cleaner than just looking at sys.argv, but it's also
going to allow us to handle the differences in the way meson and
autotools handle translations more cleanly.
