always-comparable tuple for IPython versions

Note that types for each slot must never differ, due to Python 3 breaking loose comparisons (0 is used for base micro, never '')

 """
 IPython provides a rich toolkit to help you make the most out of using Python
 interactively.  Its main components are:
 
 * Powerful interactive Python shells (terminal- and Qt-based).
 * A web-based interactive notebook environment with all shell features plus
   support for embedded figures, animations and rich media.
 * Support for interactive data visualization and use of GUI toolkits.
 * Flexible, embeddable interpreters to load into your own projects.
 * A high-performance library for high level and interactive parallel computing
   that works in multicore systems, clusters, supercomputing and cloud scenarios.
 
 The enhanced interactive Python shells have the following main features:
 
 * Comprehensive object introspection.
 
 * Input history, persistent across sessions.
 
 * Caching of output results during a session with automatically generated
   references.
 
 * Extensible tab completion, with support by default for completion of python
   variables and keywords, filenames and function keywords.
 
 * Extensible system of 'magic' commands for controlling the environment and
   performing many tasks related either to IPython or the operating system.
 
 * A rich configuration system with easy switching between different setups
   (simpler than changing $PYTHONSTARTUP environment variables every time).
 
 * Session logging and reloading.
 
 * Extensible syntax processing for special purpose situations.
 
 * Access to the system shell with user-extensible alias system.
 
 * Easily embeddable in other Python programs and GUIs.
 
 * Integrated access to the pdb debugger and the Python profiler.
 
 The parallel computing architecture has the following main features:
 
 * Quickly parallelize Python code from an interactive Python/IPython session.
 
 * A flexible and dynamic process model that be deployed on anything from
   multicore workstations to supercomputers.
 
 * An architecture that supports many different styles of parallelism, from
   message passing to task farming.
 
 * Both blocking and fully asynchronous interfaces.
 
 * High level APIs that enable many things to be parallelized in a few lines
   of code.
 
 * Share live parallel jobs with other users securely.
 
 * Dynamically load balanced task farming system.
 
 * Robust error handling in parallel code.
 
 The latest development version is always available from IPython's `GitHub
 site <http://github.com/ipython>`_.
