+ *  $LynxId: parsdate.c,v 1.30 2022/03/12 12:54:09 tom Exp $
+ *
+ *  This module is adapted and extended from tin, to use for LYmktime().
+ *
+ *  Project   : tin - a Usenet reader
+ *  Module    : parsedate.y
+ *  Author    : S. Bellovin, R. $alz, J. Berets, P. Eggert
+ *  Created   : 1990-08-01
+ *  Updated   : 2019-08-28 (by Thomas Dickey, for Lynx)
+ *  Notes     : This grammar has 8 shift/reduce conflicts.
+ *
+ *              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.
+ *              Roland Rosenfeld added MET DST code in April 1994.
+ *
+ *  Revision  : 1.13
+ *  Copyright : This code is in the public domain and has no copyright.
