DESCRIPTION
--dump Dump out grammar information
--use-devel-grammar Use the devel grammar parser from
yapps_grammar.py instead of the stable grammar from grammar.py
-fcontext-insensitive-scanner Scan all tokens (see docs)
yapps
generates a Python program which will parse a given grammar.
OPTIONS
--dump
Dump the grammar information to stdout.
--use-devel-grammar
Use the grammar file in ./yapps_grammar.py instead of yapps/grammar.py.
This option is useful for testing new grammar parsers. (Yes, yapps' parser is itself written with yapps...)
