What you are seeing is boiler-plate code automatically generated by 
setuptools (or the Distribute clone of setuptools) when a script is 
installed with easy_install.  The main reason for the wrapper is to 
allow multiple versions of a Python "package" (in the PyPi sense) to be 
installed in one Python instance.  There's more information here:
