synopsis: Happy is a parser generator for Haskell
category: Development
cabal-version: >= 1.10
build-type: Simple

Description:
  Happy is a parser generator for Haskell.  Given a grammar
  specification in BNF, Happy generates Haskell code to parse the
  grammar.  Happy works in a similar way to the @yacc@ tool for C.
