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.
