Evening, all.

This is a program written in a hurry by me one night because I was
sick of wading through 1/4M mailboxes, trying to find some archaic
piece of correspondance.  It breaks up a large mailbox (or several
of them, if you like) into smaller ones, named after the sender of
the pieces of mail they contain.  See the manual entry if this is
unclear.  Mail bugs, flames, pieces of frozen vomit, slices of
intestinal lining etc., to mirk@uk.ac.warwick.cs.  That's about it
really.  Lap it up!

PS.  1st man: "My dog's got not nose"
     2nd man: "Frog off."
