RCS release 3 is still available for free, if you retrieve it yourself over the UUCP or ARPA net. If you need a tape, there is a handlig charge of $100. In both cases, we need a signed copy of the non-disclosure form below, executed by the person who handles your Unix licenses. Upon receipt of the completed form, we will send you detailed instructions on how to retrieve RCS. If you also include the handling charge, we will mail a tape with RCS instead. The whole package consists of RCS proper, the manual pages for it, and modified versions of the Unix commands diff and diff3. If you need more information on RCS before getting it, read "Design, Implementation, and Evaluation of a Revision Control System", by Walter Tichy, in Proc. of the 6th Int'l Conference on Software Engineering, Sept. 1982, IEEE.
