#! /usr/bin/perl
# -*-Perl-*-
#
# 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.
#
# Contributed by David Hampton <hampton@cisco.com>
#
# hacked greatly by Greg A. Woods <woods@planix.com>
#
# Modified by werner.koch@guug.de to add support for
# automagically extraction of ChangeLog entries 1998-12-29
# Usage: log_accum.pl [-d] [-s] [-M module] [[-m mailto] ...] [[-R replyto] ...] [-f logfile]
# -d - turn on debugging
# -m mailto - send mail to "mailto" (multiple)
# -R replyto - set the "Reply-To:" to "replyto" (multiple)
# -M modulename - set module name to "modulename"
# -f logfile - write commit messages to logfile too
# -s - *don't* run "cvs status -v" for each file
# -w - show working directory with log message
#
# Configurable options
#
# set this to something that takes a whole message on stdin
$MAILER = "/usr/lib/sendmail -t";
#
# End user configurable options.
#
# Constants (don't change these!)
