* Revision History:
* 10-May-1997: Compatible with xscreensaver :) OK you probably should not
* use this for xscreensaver but I could not resist.
* 21-Mar-1996: Ron Hitchens <ron@idiom.com>
* Bonehead alert. Don't blank during password prompting.
* 19-Mar-1996: Ron Hitchens <ron@idiom.com>
* Changed to activate X server's native screensaver.
* On some devices, this will result in power saving "sleep"
* mode, or video blanking.
* 31-Aug-1990: Written.
