# Simple shell script that checks whether changed files contain a copyright
# statement for a given year.
#
# Rename (or symlink) this script to the year you want to check, i.e. name it
# 2002 if you want to check for copyright statements that do not contain
# the year 2002.
#
# Use this script instead of your usual cvs update command.
#
# Usage YEAR [precommit]
