+
+ # Original author: Jouni Heikniemi <[EMAIL PROTECTED]>
+ # This script was improved by Misha & Chris:
+ # * Hacked to work under Unix
+ # * Displays contents of new files (`cvs diff -r0 -r1.1')
+ # * Displays branch name in the subject line
+ # Brian Gaeke added support for people who commit via 'pserver'
+ # using the separate CVSROOT/passwd file.
