libghc-happstack-dev 6.1.8-1 (i386 binary) in ubuntu precise

 Happstack is a Haskell web framework, designed so that developers can
 prototype quickly, deploy painlessly, scale massively, operate reliably,
 and change easily. It supports GNU/Linux, OS X, FreeBSD, and Windows
 environments.
 .
 Happstack provides you with all the components you need to build and
 deploy your application, which is completely self-contained.
 Particularly, Happstack provides the application with a distributed and
 persistent data storage layer, capable to interact with the application
 itself directly in terms of Haskell data structures.
 .
 This package contains the libraries compiled for GHC.
