-# Grammar for Python
-
-# Note:  Changing the grammar specified in this file will most likely
-#        require corresponding changes in the parser module
-#        (../Modules/parsermodule.c).  If you can't make the changes to
-#        that module yourself, please co-ordinate the required changes
-#        with someone who can; ask around on python-dev for help.  Fred
-#        Drake <fdrake@acm.org> will probably be listening there.
-
-# NOTE WELL: You should also follow all the steps listed in PEP 306,
-# "How to Change Python's Grammar"
-
-# Start symbols for the grammar:
-#       single_input is a single interactive statement;
-#       file_input is a module or sequence of commands read from an input file;
-#       eval_input is the input for the eval() and input() functions.
-# NB: compound_stmt in single_input is followed by extra NEWLINE!
