     68 Byte compile some python scripts FILES.  Use --destdir to specify any
     69 leading directory path to the FILES that you don't want to include in the
     70 byte compiled file.  Specify --basedir for any additional path information you
     71 do want to be shown in the byte compiled file.
     72 
     73 Example:
     74   py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
