# Slackware build script for xcowsay

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20201103 bkw:
# - Update for v1.5.1. The changelog for this version says this:
#   Fix black squares around cow and bubble on non-compositing window manager.
#   And it works fine in the window managers I've tried it with, so
#   it's probably fine to upgrade. Add note to README about how to
#   build 1.4, if someone needs it.

# 20200221 bkw:
# - BUILD=2
# - Add man pages for xcow(dream|fortune|think)
# - Move executables to /usr/games
# - Was going to update to v1.5. See README_1.5.txt for why I didn't.
#   You're not going to convince me to upgrade to a version I can't use,
#   so don't try. Maybe 1.6 or later will support non-compositing WMs
#   at some point.
