+Grako (for grammar compiler) is a tool that takes grammars in a variation of
+EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python.
+
+Grako can also compile a grammar stored in a string into a Grammar object that
+can be used to parse any given input, much like the re module does with regular
+expressions.
