-/* $Revision$
-**
-** Originally written by Steven M. Bellovin <smb@research.att.com> while
-** at the University of North Carolina at Chapel Hill. Later tweaked by
-** a couple of people on Usenet. Completely overhauled by Rich $alz
-** <rsalz@osf.org> and Jim Berets <jberets@bbn.com> in August, 1990.
-** Further revised (removed obsolete constructs and cleaned up timezone
-** names) in August, 1991, by Rich. Paul Eggert <eggert@twinsun.com>
-** helped in September, 1992.
-**
-** This grammar has six shift/reduce conflicts.
-**
-** This code is in the public domain and has no copyright.
