Readme for happy-1.18.10

[back to package description]
This is Happy version 1.18, a parser generator for Haskell 98.

Happy is built using Cabal.  First install GHC, then:
  $ runhaskell Setup.lhs configure
  $ runhaskell Setup.lhs build
  $ runhaskell Setup.lhs install

Complete documentation can be found in the directory 'doc', in
DocBook XML format.  To format the documentation, the DocBook-Tools
suite (see http://www.
provides all the bits & pieces you need.  Alternatively, pre-formatted
documentation is available from Happy's homepage (URL above).

The directory 'examples' contains some example parsers that use Happy.
