libghc-happstack-doc 7.0.0-1build1 (i386 binary) in ubuntu quantal

 Happstack is a web framework written in Haskell; it provides a rich
 collection of types and functions for routing Requests, generating
 Responses, working with query parameters, form data, and cookies,
 serving files and more.

 This package contains the library documentation. Anyway, it is just a
 stub, depending on the package that actually provides the Happstack
 server.
