# wmmon was pretty much abandoned by the original developer 10+ years ago.
# The Debian maintainer has added some security-related fixes, a man page,
# better support for 2.6 kernels, and some extra features. Most people
# would prefer to run the patched version...
patch -p1 < $CWD/patches/${PRGNAM}_$SRCVER-$PATCHVER.diff

# This patch is necessary because the $#!%^#$^ wmmonrc file parser doesn't
# fully support comments: they are allowed, but a commented-out (but
# otherwise valid) config directive is still processed as though it
# weren't commented out! Ack!
patch -p1 < $CWD/patches/rc_file_parser.diff

# The man page refers to "the clock" (probably copied from wmclock docs),
# change to "the window".
