This won't make Python use the .pyc files provided, though. It will just recompile the .py files and then not try to write out the bytecode. If you really want to force it to use the .pyc's, then don't include the .py files. Note that if you do this, you'll need to make sure that the version of Python used to compile the .pyc files is the same minor release as the version used to run them (more specifically, the two versions must return the same string from imp.get_magic()).
