# This script updates the entire tree, saves the output in cvs.out,
# and then separately prints out the files that had merge conflicts,
# those that were merged successfully, and those that are new.
# Note that this script uses "cvs update -P -d".
#
# USAGE:
# 	cvsupdate	## normal run
# 	cvsupdate -n	## run grep commands on output of the last run of cvs
# 	cvsupdate -h	## usage information
