Actually, thinking about it more, what I'd like Orca to do is
to check if there are compressed versions of the filename (i.e.
check if filename.{Z,gz,bz2} exists and if it was created in the
last X minutes.  Otherwise, complain.  This way, if there is a
real error around midnight, then it won't be ignored.  In fact,
most errors could occur at midnight if something goes wrong with
the compression of the file.

Best,
Blair
