Berkeley Quality Software

Berkeley Quality Software adj.  (often abbreviated `BQS')
   Term used in a pejorative sense to refer to software that was
   apparently created by rather spaced-out hackers late at night to
   solve some unique problem.  It usually has nonexistent, incomplete,
   or incorrect documentation, has been tested on at least two
   examples, and core dumps when anyone else attempts to use it.  This
   term was frequently applied to early versions of the `dbx(1)'
   debugger.  See also {Berzerkeley}.

   Note to British and Commonwealth readers: that's /berk'lee/, not
   /bark'lee/ as in British Received Pronunciation.
