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. ) rA rB �isfiler rL �basename�pkgutil�get_datar rS �loads)�package�grammar_source� pickled_name�datarX r r r �load_packaged_grammar� s rg c G sB | s t jdd� } tjtjt jdd� | D ] }t|ddd� qdS )z�Main program, when run as a script: produce grammar pickle files.
