# 20241024 bkw: Modified by SlackBuilds.org, BUILD=2:
# - build with lua51.
# - make the LUAJIT option actually work (and change to yes/no, not 0/1).
# - remove special case code for CC in environment, not needed (CC=clang
#   works fine just because of how make works).
# - make the slack-desc say which lua (lua51 or luajit) was used to
#   build the package. also removed some of the long README content
#   from the slack-desc (same info is in README and the doc dir already).
