# Slackware build script for mac

# Originally written by Luis Henrique <email removed>

# Now maintained by B. Watson <urchlay@slackware.uk>

# Original version of this script had no license. Modified version
# licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/
# for details.

# 20260811 bkw:
# - update for v13.25. upstream switched to cmake, too.

# 20211125 bkw: BUILD=2
# - add -DSHNTOOL to CXXFLAGS, which enables human-readable
#   error messages (but not shn support).
# - add README note about 'invalid input file' error.
# - update README and slack-desc.
# - add man page.

# 20190107 bkw:
# - download URL went away, use netbsd pkgsrc
# - add FORCE_SLACK_CFLAGS option (probably nobody needs it)

# 20180105 bkw:
# - take over maintenance
# - update for 3.99_u4_b5_s7 (BUILD=1)
# - add ASM environment variable
# - don't install INSTALL in doc dir
# - get rid of .la file
# - minor script simplification
