68Byte compile some python scripts FILES.  Use --destdir to specify any
69leading directory path to the FILES that you don't want to include in the
70byte compiled file.  Specify --basedir for any additional path information you
71do want to be shown in the byte compiled file.

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