Please excuse me if this is old news... I myself didn't know about it
until today... but it would seem that the file(1) command on both FreeBSD
and Linux implements a -i option that nicely spits out an appropriate
MIME type for the file being examined.

I haven't looked to see if the attach command for whatnow is using that
or not, but certainly, if it is (or if it will, in the future), then it
would seem to me that whatnow itself would not even need to make use of
any file called "mime.types" (no matter where located).

(Just tryin' to be helpful... on the off chance that I am not the only one
on this planet who didn't know already know about this -i option.)
