(synopsis "Create Haskell bindings to C libraries")
(description "C->Haskell assists in the development of Haskell bindings to
C libraries. It extracts interface information from C header files and
generates Haskell code with foreign imports and marshaling. Unlike writing
foreign imports by hand (or using hsc2hs), this ensures that C functions are
imported with the correct Haskell types.")
