# 20240313 bkw: update for v1.7.1.
# 20231108 bkw: update for v1.7.0.
# 20230808 bkw:
# - take over maintenance.
# - update for v1.6.1.
# - update README for modern Slackware.
# - remove useless INSTALL from doc dir.
# - add contrib/* to doc dir.
# - patch crond so it accepts (and ignores) "-l notice", so we don't have
#   to change Slackware's init stuff.
# - add /etc/rc.d/rc.crond and /etc/default/crond.
# - gzip run-parts man page.
