The BNF Converter is a compiler construction tool that generates a compiler front-end and a readable syntax description document from a Labelled BNF grammar. It was originally written to generate Haskell, but it can now also be used for generating Java, C++, and C.

To process Haskell output, you need the Glorious Glasgow Haskell Compiler (virtual package ghc), the Happy parser generator (package happy) and the Alex scanner generator (package alex).

To process Java output, you need a Java compiler and virtual machine, the CUP parser generator (package cup) and the JLex scanner generator (package jlex).
