  execnet: distributed Python deployment and communication
  ========================================================
  
  .. _execnet: http://codespeak.net/execnet
  
  execnet_ provides carefully tested means to ad-hoc interact with Python
  interpreters across version, platform and network barriers.  It provides
  a minimal and fast API targetting the following uses:
  
  * distribute tasks to local or remote processes
  * write and deploy hybrid multi-process applications
  * write scripts to administer multiple hosts
  
  Features
  ------------------
  
  * zero-install bootstrapping: no remote installation required!
  
  * flexible communication: send/receive as well as
    callback/queue mechanisms supported
  
  * simple serialization of python builtin types (no pickling)
  
  * grouped creation and robust termination of processes
  
  * well tested between CPython 2.6-3.X, Jython 2.5.1 and PyPy 2.2
    interpreters.
  
  * interoperable between Windows and Unix-ish systems.
  
  * integrates with different threading models, including standard
    os threads, eventlet and gevent based systems.
