        XMPP allows for an agent to advertise the name and version of the
        underlying software libraries, as well as the operating system
        that the agent is running on.

        Example version stanzas:
        ::

              <iq type="get">
                <query xmlns="jabber:iq:version" />
              </iq>

              <iq type="result">
                <query xmlns="jabber:iq:version">
                  <name>Slixmpp</name>
                  <version>1.0</version>
                  <os>Linux</os>
                </query>
              </iq>

        Stanza Interface:

        ::

            name    -- The human readable name of the software.
            version -- The specific version of the software.
            os      -- The name of the operating system running the program.
