# This is a script suitable for running once a day from a cron job.  It

# assigned to them that has status CONFIRMED, NEW, or REOPENED that has not
# been touched for more than the number of days specified in the whinedays
# param. (We have NEW and REOPENED in there to keep compatibility with old
# Bugzillas.)
