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

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