# Slackware build script for xzoom

# The _26 is the Debian patchlevel. They've done a lot to this, such as
# support for >8bpp displays... since it's the future now, everyone's
# using 24/32bpp, so the Debian maintainers rescued xzoom from the
# scrap heap. Thanks!

# Note about versions: repology.org thinks I should update this
# to 0.4. Debian's 0.3-26 and FreeBSD's 0.4 are both forks from the
# original 0.3. The Debian fork has fixes and enhancements that aren't
# in 0.4, plus all the features that are in 0.4. One of the features
# that's in 0.3-26 but not 0.4: the xmag window has a real close
# button. If you're about to ask me to update this to 0.4, don't. I
# won't. It's not actually an update (despite the version number, it
# would actually be a downgrade).

# 20230906 bkw: BUILD=2, update man page slightly.
