# RCS cleanup operation.
# $Header: /var/lib/cvsd/repos/CSRG/43BSDTahoe/new/rcs/src/rcsclean.sh,v 1.1.1.1 2018/04/24 16:12:58 root 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.
