   6 # This program removes working files which are copies of the latest
   7 # revision on the default branch of the corresponding RCS files.
   8 # For each file given, rcsclean performs a co operation for the latest
   9 # revision on the default branch, and compares
  10 # the result with the working file. If the two are identical,
  11 # the working file is deleted.
  12 #
  13 # A typical application in a Makefile would be:
  14 # clean:;       rm *.o; rcsclean *.c *.o
  15 #
  16 # Limitation: This program doesn't work if given the name of
  17 # an RCS file rather than the name of the working file.
