HOPPET constants
================

Auto-generated constants reference for the `hoppet` module.

PDF indices
-----------

These are the PDF indices of lists that are returned by e.g. :func:`Eval` or that are to be passed to :func:`EvalIFlv`.
        Note that index 13, not listed below, is used to encode information about the PDF flavour representation.
