Some other modules (eg pyserial-pyparallel) also conditionally import modules for each platform. (see EncodingsAgain and EvenMoreEncodings). If you use a feature that requires encodings, you will need to put an option to include encodings unconditionally or to import them explicitly from one of your script. For examples, encodings are imported 'by name'. But it might happen that these are not enough. To run your program needs all these files.
Some pyd probably have some DLL dependencies, and here they come Those files also follow into the subdirectory where library.zip will be installed Also they are necessary to provide support to native functions of the operating system (see also CTypes to never have to use SWIG again!). Some applications build pyd to provide accelerated features. They are also standard modules for Python. The pyd files are actually standard Windows DLL (I used the useful depends.exe to check things around). This is a standard zip file where all the pure source modules will be inserted (using the 'zipfile' option, you can also select to put that file in a sub-directory and with a different name) You can select a custom icon by using some specific target options (see CustomIcons)
