/***************************************************************************************
* MODULE NOTES -- MTBF -- Mean Time Between Failures
* @update gess 01/04/99
* @update cyeh 03/15/99
*
* MTBF is a simple WinNT application that runs our viewer.exe remotely.
* After viewer crashes (inevitably) the total elapsed time is recorded, and send
* in an HTML mail message to the appropriate recipient. By default, the message
* is sent to rickg, but you can cause it to be sent to anywhere you like.
*
* Note: To compile this program using the existing project file, simply create a
* subst drive on your system using s:\ as the root. Place this project
* there as s:\mtbf. Of course, if this doesn't work for you, it's easy
* to change since there's only one file in the whole project anyway.
*
* Note: We depend on the availability of the blat.exe somewhere in your path.
* You can get your own copy of BLAT at http://gepasi.dbs.aber.ac.uk/softw/Blat.html.
