+enumerations are split into sum types, and we perform automatic
+error-checking.  The @code{SDL.Raw} namespace contains an almost 1-1
+translation of the C API into Haskell FFI calls.  As such, this does not
+contain sum types nor error checking.  Thus this namespace is suitable for
+building your own abstraction over SDL, but is not recommended for day-to-day
+programming.")
