Well, simply adding an "H" probably wouldn't convince a lawyer...

Things have changed drastically in the CVS version, you should be able to build it easily when configuring GHC with --enable-hopengl. GLUT's API is built heavily upon the OpenGL concept of a state variable, and this is now reflected on the Haskell side. Have e.g. a look at the size of the current window, it's type is now: windowSize :: StateVar Size No different functions for getting it and setting it, just use: windowSize $= Size 400 300 and size <- get windowSize State which can only be read has another type, e.g.: parentWindow :: GettableStateVar Window You can do parent <- get parentWindow but parentWindow $= <whatever> will result in a type error. Similar things hold for write-only state. In Marks's spirit, this is still exactly the GLUT API, but without the restrictions of the C language. The docs are consequently quite different, too, but are of course based on what I've read about GLUT's C API. Frankly, I don't really care about the legal status of my docs anymore, and will leave it in HOpenGL. If some distributions have a problem with this, so be it... I've done the best I could do to clarify this and made no gratuitous additions to GLUT (which is exactly what Mark tries to prohibit). As an aside, I've got the permission to base my OpenGL docs on SGI's man pages without any trouble. Things are sometimes easy... :-] Cheers, S.
