# Short-Description: Zope MaildropHost queue manager
# Description:       Zope MaildropHost is an alternative implementation of the
#                    Zope MailHost product. MaildropHost is different in that
#                    it doesn't send mails out immediately. Instead, mails are
#                    written to a queue.
#                    A seperate daemon - the queue manager - processes the
#                    queue regularly. This script manages the queue manager.
