     60 Byte compile some python scripts FILES.  Use --destdir to specify any
     61 leading directory path to the FILES that you don't want to include in the
     62 byte compiled file.  Specify --basedir for any additional path information you
     63 do want to be shown in the byte compiled file.

     65 Example:
     66   py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
