+About Apache Vysper
+This project aims at delivering a server implementation of both the core and IM parts of the XMPP protocol
+(as specified in RFCs 3920 [1] + 3921 [2]).
+"Vysper" is pronounced like in "whisper".
+XMPP[3] is an open, secure and extensible instant messaging protocol which has evolved from Jabber.
+It provides interoperability features for communication with other XMPP and non-XMPP servers.
+It is used and supported by many IM applications, both client and server.
+The protocol and its many extensions (called XEPs) are maintained by the XMPP Standards Foundation (XSF) [4].

+The system architecture is separated into parts:
+* Abstract protocol handling *
+package: o.a.v.xmpp.protocol
+Protocol workflow, state machine changes during handshake, consistency checks
+Delegation to concrete handling
+* Concrete protocol handling *
+package: o.a.v.xmpp.applicationdomains
+Stanza handlers and Response builders
+Concrete processing of stanzas
+* XML parsing into fragments XMPP
+package: o.a.v.xmpp.xmldecoder
+Determines stanza boundaries in a sequence of characters and translates into (potential) XMPP stanzas
+* Server runtime incl. session handling
+server instance with all its properties and switches.
+* Stanza infrastructure and tools
+packages: o.a.v.xmpp.stanza, o.a.v.xmpp.xmlfragment
+handles stanza objects freed from any representation (XML)
+* TCP binding
+package: o.a.v.mina
+binding to TCP protocol endpoint, handling endpoint events, delivering data from/to XML parsing
+* SASL authorization mechanism logic
+package: o.a.v.xmpp.authorization
+* SEDA: staged event driven architecture
+available stages:
+reading from TCP/IP socket - XMLStreamTokenizer
+handling inbound stanzas from client - QueuedStanzaProcessor
+handling outbound stanzas to clients - DeliveringStanzaRelay
+missing stages:
+handling outbound stanzas to servers - RecordingStanzaRelay (provisorial implementation)
+handling inbound stanzas issued by self or remote servers (to go to clients or not) - missing!

+** Contributing **
+You can contribute by creating a new JIRA issue entry (or working on an existing).
+JIRA can be found at
+You need an account there.
+Go to category LABS, component VYSPER.
+Useful URL:
+Any contribution should come in form of a patch attached to a JIRA entry.
+Currently, all coding is done unit test driven. Well, at least it should ;-)
+** Tools **
+Apache Ant is used as the build tool.
+** Compiling **
+ant compile.vysper
+** Running Unit Tests **
+ant run-unit-tests
+** Running the Server **
+ant run-server
+Server is started using class org.apache.vysper.spring.ServerMain
+** Running a test client **
+A Smack-based client can be run against the server by executing main class org.apache.vysper.smack.BasicClient
+The client also opens a UI logging all stanzas
