Description_File

   The description file contains rules that describe how the  components
   of  your system are related and how MMS is to build them.  You create
   and modify  a  description  file  with  any  text editor (or by using
   MMS/GENERATE);  once the description file exists, you need issue only
   a simple MMS command to update your system.

   A description file contains dependency rules  and  can  also  contain
   macro definitions, directives, and user-defined rules.
