# 20260701 bkw:
# - take over maintenance.
# - update for v1.26.
# - remove INSTALL from doc dir (not needed in binary pkg).
# - actually use SLKCFLAGS (they were being ignored).
# - add doinst.sh (and douninst.sh) for /usr/info file.
# - improve grammar in README and slack-desc (nitpick).
# - expand README (with description from man page).
