# Slackware build script for icebreaker

# Written by B. Watson (urchlay@slackware.uk)

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

# 20241124 bkw: updated for v2.2.2+7180612_20231115. There's no new
# release, but this version fixes a potential security flaw (buffer
# overrun), so it's worth upgrading to IMO.

# 20230107 bkw: Updated for v2.2.1! After 20+ years, the author came
# back to this game and released a new version.

# 20170703 bkw: Updated for v1.9.7, the last beta, with theme support.
# Development on this game stopped in 2002, so there will never be a 2.0
# release. If anyone finds bugs in 1.9.7, let me know.

# 20211019 bkw: BUILD=3
# - move high score file to /var/games/icebreaker, to match other
#   games on SBo.
# - include README.themes in doc dir.
# - new-style icons.
