# Bugzilla email script for Bugzilla 2.17.4 and later.  Invoke this to send
# bugmail for a bug which has been changed directly in the database.
# This uses Bugzilla's own BugMail facility, and will email the
# users associated with the bug.  Replaces the old "processmail"
# script.
# 
# Usage: perl -T contrib/sendbugmail.pl bug_id user_email
