Description: 
        Overview
        --------
        
        The ``cdecimal`` package is a fast drop-in replacement for the ``decimal`` module
        in Python's standard library. Both modules provide complete implementations of
        Mike Cowlishaw/IBM's ``General Decimal Arithmetic Specification``.
        
        Testing
        -------
        
        Both ``cdecimal`` and the underlying library - ``libmpdec`` - are extremely
        well tested. ``libmpdec`` is one of the few open source projects with 100%
        code coverage. ``cdecimal`` is rigorously tested against ``decimal.py``.
        
        Short benchmarks
        ----------------
        
        Typical performance gains are between 30x for I/O heavy benchmarks
        and 80x for numerical programs. In a database benchmark, cdecimal
        exhibits a speedup of 12x over decimal.py.

        Documentation
        -------------
        
        Since ``cdecimal`` is compatible with ``decimal.py``, the official documentation
        is valid. For the few remaining differences, refer to the second link.
        
        * `Decimal module <http://docs.python.org/dev/py3k/library/decimal.html>`_
        * `Differences between cdecimal and decimal <http://www.bytereef.org/mpdecimal/doc/cdecimal/index.html>`_
        
        Linux Notes
        -----------
        
        The build process requires a working C compiler and a *full* Python install with
        development headers. Linux distributions often ship the Python header files as
        a separate package, called *python-dev* or *python-devel*.
        
        Install headers on Debian/Ubuntu:
        
        * ``sudo apt-get install python-dev``
