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