RCS is copylefted, which is not the same as public domain, but it does mean the
source is freely available.  You can FTP it from the following sites:

    site                filename
    archive.cs.ruu.nl   /pub/GNU/rcs-5.5.tar.Z
    cs.purdue.edu       pub/RCS/rcs.5_5.tar.Z
    prep.ai.mit.edu     pub/gnu/rcs-5.5.tar.Z
    uunet.uu.net        gnu/rcs-5.5.tar.Z

It works best with GNU diff 1.15; look for diff-1.15.tar.Z.
