|�|S)a�Normally, loads a pickled grammar by doing
        pkgutil.get_data(package, pickled_grammar)
    where *pickled_grammar* is computed from *grammar_source* by adding the
    Python version and using a ``.pickle`` extension.

    However, if *grammar_source* is an extant file, load_grammar(grammar_source)
    is called instead. This facilitates using a packaged grammar file when needed
    but preserves load_grammar's automatic regeneration behavior when possible.
