compiler front-end from a Labelled BNF grammar. It was originally
written to generate Haskell, but starting from Version 2.0, it can
also be used for generating Java, C++, and C.
Given a Labelled BNF grammar the tool produces:
* an abstract syntax as a Haskell/C++/C module or Java directory
* a case skeleton for the abstract syntax in the same language
* an Alex, JLex, or Flex lexer generator file
* a Happy, CUP, or Bison parser generator file
* a pretty-printer as a Haskell/Java/C++/C module
* a Latex file containing a readable specification of the language
