CMS

   Code Management System for OpenVMS (CMS) is a library system 
   for software development and maintenance. CMS stores source 
   files in a library, keeps track of changes made to the files, 
   and records user access to the files.

   If you have installed DECwindows on your system, you can also 
   use the CMS DECwindows interface (CMS Version 3.2 and higher).  
   See the /INTERFACE qualifier for information on invoking the 
   CMS DECwindows interface.
