# In English, the if/find below means "only run the database creation if
# it was last done over an hour ago". This is needed because upgradepkg
# runs doinst.sh twice, but I don't want the 10+ minute long database
# creation to happen twice on upgrade (or at all, when I'm repeatedly
# reinstalling man-db for testing purposes).

# Generate the initial man database (or rebuild it if it exists).
# We want to skip this step if installing somewhere besides / (e.g. with
# the -root option or ROOT env variable set for installpkg), hence the
# readlink silliness.
# The -c option means it blows away any existing db. I thought about
# leaving it off (it will still create the db if it doesn't exist),
# but decided it's better to build it fresh if the package gets
# reinstalled (in case the db format has changed, or in case the
# db is corrupted and the user is trying to fix it by reinstalling
# this package).
# the 2>/dev/null was added for 2.7.6 because it complains about
# missing CACHEDIR.TAG files... which don't matter, because we've
# got NOCACHE in the config file.
