# macOS 10.15 "Catalina" has some major issues.
# The whatis database is non-existent, so apropos tries (and fails) to create it every time,
# which takes about half a second.
#
# Instead, we build a whatis database in the user cache directory
# and override the MANPATH using that directory before we run `apropos`
#
# the cache is rebuilt once a day
