Does the distutils "clean" option work on MS Win32 platforms? Here is the result on my computer: D:\my-py-pkgs\GOES-12-SXI-GDS-processor-v4.0>setup.py clean running clean warning: clean: 'build\temp.win32-2.2' does not exist -- can't clean it which is not surprising since the build directory created by "setup.py install" is not 'build\temp.win32-2.2'.
