/*
 *  VER.C - ver internal command.
 *
 *
 *  History:
 *
 *    06/30/98 (Rob Lake)
 *        rewrote ver command to accept switches, now ver alone prints
 *        copyright notice only.
 *
 *    27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
 *        added config.h include
 *
 *    30-Jul-1998 (John P Price <linux-guru@gcfl.net>)
 *        added text about where to send bug reports and get updates.
 *
 *    20-Jan-1999 (Eric Kohl)
 *        Unicode and redirection safe!
 *
 *    26-Feb-1999 (Eric Kohl)
 *        New version info and some output changes.
