Hi Jamey,

I am a GTK user yet.
GTK is nice but I do not consider GUI libs such as GTK and Qt as the universal 
perfect answer for all kinds of softwares. For exemple I do love a lot the 
GUI of Blender. Unfortunatly it doesn't seems to be abstracted form the soft 
yet as a lib. (There's ghost but it seems to be only a replacement for glut, 
and perhaps I'm wrong, but it seems that ghost does not provide all the 
widgets used in the Blender's GUI.)

There are cases where I think low level raw X is the answer
- when one do not want a conventional GUI like GTK and Qt are (: blender like)
- when one wish to make demos or screensavers
- when one wish to make a 2D game ?

(if I'm wrong with these cases, please tell me)

It seems much harder to install too  :p  ;-)
However, I would like to install it since I've started to try to make the very 
early alpha beginning of a binding of the xlib for OCaml,
OCaml is designed to be high level, efficient and _safe_, and the problem when 
mixing OCaml and C code is that the safety is compromised by the C part, and 
I've read that you work on the formally aspect with the XCB, which I guess a 
lot of OCaml users would appreciate.

I don't know if I will succeed the XCB install, so I have a question:
 what do you think would be the best choice, to bind the xlib for OCaml, or 
writing an X library in ocaml ?

++ Best Regards, Florent
