I still feel like unzipping and checking the extensions of the
files contained.  I saved the perl posted here and will try it
when I get a chance.

There are legit reasons to use zip files and I want to preserve
the functionality if we can.  But some of our people lost major
amounts of work by opening NetSky zip files, and we have been
charged with preventing further cases.

The idea of hiring an army of orphans to carry envelopes around
campus has been suggested.  Attach images with paper clips.  It's
sounding better every day, but there is apparently some sort of
limit on child labor that Counsel will have to check on.
