The config dirs stuff looks good.  Systems and sources do not belong under
DATA dirs.  If the cache path specifies where fasls get dumped, I'm
ambivalent whether it belongs in CACHE_HOME.

Are there specs regarding how XDG works on apple or mswin platforms?

Also note that systems like KDE support XDG in addition to their own
heirarchy.  There are benefits to keeping your apples away from your
oranges.

XDG is a win if you're trying to share trash cans and desktop files
between window managers.  I don't see how CL fits in; but XDG does appear
to have a reasonable description of how things work.
