   The authors would like to acknowledge the substantial contributions
   made by the members of the following two groups, the Federal
   Engineering Planning Group (FEPG) and the International Engineering

   MA in July 1992.

   We would also like to thank Peter Ford (Los Alamos National
   Laboratory), Elise Gerich (MERIT), Steve Kent (BBN), Barry Leiner
