libghc-happstack-prof 7.0.1-2build1 (amd64 binary) in ubuntu saucy

 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 profiling libraries compiled for
 GHC. Anyway, it is just a stub, depending on the package that
 actually provides the Happstack server.
