High-level Python API Reference

The vc2_bit_widths Python module exposes the underlying functionality provided by the command-line utilities (see Command-line utilities reference) via a Python interface. In addition, Python functions are provided for assisting in the serialisation and deserialisation of the file formats used by the command-line utilities.
