.pyc files do not increase the speed of execution -- only the speed of
importing modules. Even then, the benefit is only seen the first time
the modules are loaded, as the .pyc files will be generated
automatically. I'd say the tiny, one-time speedup isn't worth it; and
if you really want the modules to be precompiled, it's better to do it
at installation time using distutils.
