/*
* 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.
