Grammatica

Grammatica is a parser generator (compiler compiler) for C# and Java. It improves upon similar tools (like yacc and ANTLR) by creating well-commented and readable source code, by having automatic error recovery and detailed error messages, and by support for testing and debugging grammars without generating source code. Grammatica supports LL(k) grammars with an unlimited number of look-ahead tokens.
