  65 Usage: py-compile [--help] [--version] [--basedir DIR] [--destdir DIR] FILES..."
  66
  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.
  71
  72 Example:
  73   py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
