        """
        translates the helpers to C code using SymEngine’s `C-code printer <https://github.com/symengine/symengine/pull/1054>`_.

        Parameters
        ----------
        chunk_size : integer
            If the number of instructions in the final C code exceeds this number, it will be split into chunks of this size. See `large_systems` on why this is useful.

            If there is an obvious grouping of your helpers, the group size suggests itself for `chunk_size`.

            If smaller than 1, no chunking will happen.
