python-pyxmpp 1.1.2-1 (arm64 binary) in ubuntu zesty

 PyXMPP is a Python XMPP (RFC 3920,3921) and Jabber
 (http://www.jabber.org/protocol/) implementation. It is based on libxml2 --
 fast and fully-featured XML parser.
 .
 PyXMPP provides most core features of the XMPP protocol and several
 JSF-defined extensions. PyXMPP provides building blocks for creating Jabber
 clients and components. Developer uses them to setup XMPP streams, handle
 incoming events and create outgoing stanzas (XMPP "packets").
 .
 Features:
  * nearly complete XMPP Core (RFC 3920) protocol for client connections
    (includes SASL, TLS and Stringprep)
  * mostly complete XMPP IM (RFC 3921) protocol (lacks privacy lists)
  * XMPP error objects including translations to and from legacy codes for
    backward compatibility (JEP-0086).
  * legacy authentication ("digest" and "plain") (JEP-0078).
  * component protocol (JEP-0114).
  * Service Discovery (JEP-0030).
  * vCards -- both Jabber "vcard-temp" and RFC 2426
  * basic parts of the Multi-User Chat protocol (JEP-0045)
  * delayed delivery timestamps (JEP-0091).
