Introduction
============
This is an implementation of the server bits of [XEP-0357: Push
Notifications](http://xmpp.org/extensions/xep-0357.html). It allows
clients to register an "app server" which is notified about new messages
while the user is offline or disconnected. Implementation of the "app
server" is not included[^1].
Details
=======
App servers are notified about offline messages.
Installation
============
Same as any other module.
Configuration
=============
Configured in-band by supporting clients.
Future
======
Adding support for sending notifications for users who are online but
not currently connected, such as when `mod_smacks` is keeping their
session alive, should be added.
[^1]: The service which is expected to forward notifications to
something like Google Cloud Messaging or Apple Notification Service
