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. ) rK rL �isfiler rV �basename�pkgutil�get_datar r] �loads)�package�grammar_source� pickled_name�datarb s r �load_packaged_grammarrs � sf � � �w�w�~�~�n�%��N�+�+�(����)9�)9�.�)I�J�L� � � �G�\� 2�D�����A��G�G�D�M� �Hr c � � | st j dd } t j t j t j d�� | D ] }t |dd�� � y)z�Main program, when run as a script: produce grammar pickle files.
