 description:
   Qtah is a set of Qt bindings for Haskell.  This package is a Hoppy FFI
   generator.  You shouldn't need it directly; rather, qtah-cpp and qtah use it
   as part of their build processes.

--- This library is necessary so that qtah-cpp and qtah can build-depends on
--- qtah-generator.  build-depends requires a library in the target package.
--- build-tools can't be used because these don't get installed automatically[1]
--- and Cabal also complained about not being able to find the versions of the
--- qtah-generator binary, when I tried to specify version dependencies.
---
--- This library has an empty module so that "cabal haddock" doesn't fail.
