supports two methods of change synchronization:
locking model – All work files are read-only. A user must lock
the file in order to edit it. When the user check-in the
changes, he or she must unlock the file in order to
enable other users to edit the file.
changes model (CVS) – All users may always edit all files.
When a file is checked-in, CS-RCS merges the edits
automatically into the repository. In the case of conflicts,
CS-RCS activates the CSDiff tool to visually display and
solve the conflicts. (Conflicts may happen if the same
line has been changed by two users.)
