A port of RCS 4.2 (revision control system, source code control system)
to MS-DOS appeared with sources a few days ago in the comp.binaries.ibm.pc
newsgroup. I made diffs to plain rcs 4.2 and applied them to plain rcs 4.3
which I had available and made some additional changes.

To compile, MS C 6.00 is required, 5.10 does not work (lib functions).
To use it, you need GNU diff.

The following changes were made:
- Restrictions of file name length were removed, it should now work
  with HPFS names. Be shure to use the .DEF files because of the flag.
- The author of the DOS port changed the interpretation of path names
  to recognize \ instead of / as separator *only*. I have tried to make
  it recognize *both* separators. I hope that I found all places.
- On output, RCS converts path names now to lowercase and / separators.
  I think that's better because it is (originally) a Unix program.
- Under Unix it is semantically correct to delete an open file but not
  under DOS and OS/2. This is used by RCS and was not corrected by the
  DOS port. DOS does not refuse deletetion of open files (DOS = dumb
  operating system) while OS/2 of course does so. Some changes were
  needed to correct this.
- The USER environment variable is also recognized (besides USR).
- A bug in the spawning routine caused redirected stdio files to
  remain open after the spawn and thus made them unremovable.

Note:
RCSMERGE does not (yet) work. In addition to GNU diff, it also requires
diff3, sh and ed. I have all of them for OS/2 (sh should appear in comp.
binaries.os2 real soon) but the ed clone seems to have problems handling
output from GNU diff3. The shell script merge.sh was adapted to OS/2
and is included as merge.cmd in the following shar.
