This program is intended to be executed by the local mail delivery agent
after it has processed an incoming message.  A recipient and message must be
provided.  The recipient's Jabber ID may be retrieved from a database or
related to her E-Mail address by some simple heuristic.  The notification
message should contain some part of the incoming message header.

Execute with a parameter of "--check" to check the validity of the
configuration file.

For proper operation, Mail Hail must be registered with the Jabber server.
Execute once with a parameter of "--register" after installing a new
configuration file.
