The System ModeUer provides automatic support for several different kinds of program development cycle in the Cedar programming system. It handles the daily evolu-tion of a single module or a small group of modules modified by a single person, the assembly of numerous modules into a large system with complex interconnec-tions, and the formal release of a system. The Modeller can also efficiently locate a large number of modules in a big distributed file system, and move them from one machine to another to meet operational requirements or improve performance.
