Mnesia question

I'm not absolutely sure, but I would guess that trex is
badly (though unofficially) deprecated. To my knowledge, it
is no longer used by those who wrote it in the first place.

(If this is true, it should probably be removed from the
contribs directory...? Could someone who feels closer to
trex verify?)

The OTP table visualizer does many of the things trex does.
Perhaps you should go with that first?
