synopsis:        A yacc-like frontend for happy

Description:
  Happy is a parser generator for Haskell.
  Happy-Frontend is responsible for parsing .y- and .ly-files
  and mangling them into a Grammar datatype.
  These .y- and .ly-files work similar to yacc's .y-files, but
  have some Haskell-specific features.
