* 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 <[email protected]>)

* added config.h include

* 30-Jul-1998 (John P Price <[email protected]>)

* 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.
