__doc__ = """
This compatibility module is inspired by the one found
in CherryPy. It provides a common entry point for the various
functions and types that are used with ws4py but which
differ from Python 2.x to Python 3.x

There are likely better ways for some of them so feel
free to provide patches.

Note this has been tested against 2.7 and 3.3 only but
should hopefully work fine with other versions too.
