Event Index
===========
Slixmpp relies on events and event handlers to act on received data from
the server. Some of those events come from the very base of Slixmpp such
as :class:`~.BaseXMPP` or :class:`~.XMLStream`, while most of them are
emitted from plugins which add their own listeners.
There are often multiple events running for a single stanza, with
different levels of granularity, so code must take care of not
processing the same stanza twice.

Dedicated PubSub Events
=======================
The :class:`~.XEP_0060` plugin (and :class:`~.XEP_0163` plugin, which uses
the former) allows other plugins to map specific namespaces in
PubSub notifications to a dedicated name prefix.
The current list of plugin prefixes is the following:
- ``bookmarks``: :class:`~.XEP_0048`
- ``user_location``: :class:`~.XEP_0080`
- ``avatar_metadata``: :class:`~.XEP_0084`
- ``avatar_data``: :class:`~.XEP_0084`
- ``user_mood``: :class:`~.XEP_0107`
- ``user_activity``: :class:`~.XEP_0108`
- ``user_tune``: :class:`~.XEP_0118`
- ``reachability``: :class:`~.XEP_0152`
- ``user_nick``: :class:`~.XEP_0163`
- ``user_gaming``: :class:`~.XEP_0196`
