Description: Extensible library for handling the XMPP protocol (RFC 3920). This code is inspired by, but not derived from, https://github.com/mattn/go-xmpp/.  The core of the protocol is handled by xmpp.go, structs.go, and stream.go. Everything else is an extension, though some of the provided "extensions" are mandatory pieces of the protocol. Many of the XEPs at http://xmpp.org/xmpp-protocols/xmpp-extensions/ can be supported by this library, though at present only base protocol support is here.  An simple client using this library is in the example directory. A more interesting example can be found at https://cjones.org/hg/foosfiend.
