/***************************************************************************************
 * MODULE NOTES -- MTBF -- Mean Time Between Failures
 * @update  gess 01/04/99
 *
 *  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.
