# Perl filter to handle the log messages from the checkin of files in
# a directory. This script will group the lists of files by log
# message, and mail a single consolidated log message at the end of
# the commit.
#
# This file assumes a pre-commit checking program that leaves the
# names of the first and last commit directories in a temporary file.
