class_docstr: Enhanced 'build_py' command that includes data files with packages
  
  The data files are specified via a 'package_data' argument to 'setup()'.
  See 'setuptools.dist.Distribution' for more details.
  
  Also, this version of the 'build_py' command allows you to specify both
  'py_modules' and 'packages' in the same setup operation.
