# 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
