# rcsclean - remove working files that are copies of the latest RCS revision
# $Id: rcsclean.sh,v 1.7 1990/11/13 15:46:17 hammer Exp $
# This program removes working files which are copies of the latest
# revision on the default branch of the corresponding RCS files.
# For each file given, rcsclean performs a co operation for the latest
# revision on the default branch, and compares
# the result with the working file. If the two are identical,
# the working file is deleted.
#
# A typical application in a Makefile would be:
# clean:; rm *.o; rcsclean *.c *.o
#
# Limitation: This program doesn't work if given the name of
# an RCS file rather than the name of the working file.
