# 20230106 bkw: update for v4.2.4. also gzip the man page...

# 20211213 bkw: This replaces the ancient grip2 build. We didn't have
# grip 3.x builds because they had too many gnome dependencies; the
# 4.x series dropped those and is a pure GTK+ application. Except for
# its Help option, which requires yelp. To avoid a dependency on yelp,
# I convert the docs to HTML and patch grip to open a browser.
