Readme for happy-1.19.2

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

   http://www.haskell.org/happy/
   http://hackage.haskell.org/cgi-bin/hackage-scripts/package/happy

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.http://sourceware.cygnus.com/docbook-tools/)
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.

For information on copying and distributing this program, see the file
