# 20170305 bkw:
# - get rid of systemd-specific /usr/lib/tmpfiles.d from package.
# - patch configure so it doesn't write to /usr/lib.

# 20170215 bkw:
# - update for 2.7.6.1 (whoops, last update wasn't for the latest version
# - only update the cache in doinst.sh if it's over an hour old. this
#   takes several minutes, and happens twice (uselessly) if the package
#   is upgraded (since üpgradepkg runs doinst.sh twice). waiting an hour
#   also makes my life easier when I'm testing this script.
# - fix man-db.cron so it works even if USR=yes (whoops), and stop trying
#   to chown the cache to the nonexistent 'man' user.

# 20170125 bkw:
# - update for 2.7.6.
# - add --disable-cache-owner. TODO: revisit this at some
#   point. Maybe create a dedicated 'man' user, or use one of the existing
#   users like 'bin' or 'operator'.

# 20160726 bkw:
# - update for 2.7.5.

# 20150507 bkw:
# - update for 2.7.1.
# - fix homepage in .info file.
# - had to update libpipeline to 1.4.0.

# 20140924 bkw:
# - update for 2.7.0.1, which fixes the clash between man-db's zsoelim
#   and groff's zsoelim.
# - update README and README.Slackware slightly.

# go to /opt. Everything else (libpipeline, man-db's shared libs, localized
# messages, etc) goes to /usr as usual.
