# Now maintained by B. Watson <yalhcru@gmail.com>

# 20180629 bkw:
# - Take over maintenance.
# - BUILD=2.
# - Stop spamming /etc/X11/app-defaults and /usr/bin (!!)
# - Add -DHAVE_GUNZIP and -DHAVE_BUNZIP2 options, to support viewing
#   compressed images.
# - Install xliguide.5 man page.
# - Make system-wide config file actually work as documented in the
#   man page. Previous it was getting installed (straight to /etc, not
#   as part of the package!) and totally ignored at runtime.
# - Include chkgamma.jpg in doc dir, since ABOUTGAMMA references it.

# TODO: find out why "-border" doesn't seem to work. The -fullscreen
# window border is always white, no matter what color you give to
# -border. I only moderately care about this, TBH.
