# Slackware build script for mksh

# Original author: Markus Reichelt, Aachen, DE
# Now maintained by B. Watson <urchlay@slackware.uk>

# 20230706 bkw:
# - only run test.sh if both stdin and stdout are TTYs.

# 20230102 bkw: BUILD=2
# - take over maintenance.
# - relicense as WTFPL.
# - install FAQ.htm, not mksh.faq.
# - make the test suite optional (but default to enabled).
# - simplify the build script.
# - make the slack-desc show the build options.
