  67
  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
