Introduction

1. Revision control, what is it?

2. Typical RCS activities:

   

3. Various implementations: RCS, SCCS.

4. Accessing previous versions.

5. File ``locking.'' Read-only versus read-write access.

6. Limitations:
   1. All revisions kept in a single file.

   2. ``Locking'' easily circumvented.

   3. Locking only meaningful when multiple userids access a file.

7. Revision numbers: major, minor.

   When to bump the major number?

8. The RCS directory.
