OCamlSDL2 is an OCaml interface to the SDL2 library.
If you are searching for OCaml bindings for SDL 1.2 then you should go there instead: ocamlsdl.sf.net
Why another OCaml SDL bindings?
SDL1 was released under the LGPL and OCamlSDL1 too. (LGPL without any exception on static linking.) SDL2 is released under a liberal license. And it was impossible to reach the authors of OCamlSDL1 to ask them to change the license. If SDL changes again its license in the future to any Floss / OSI approved license, you can use these bindings under the terms of the same license.
These relays are currently in a very early draft state. You may expect to get segfaults. These pieces of code are currently called "relays" and not bindings while there is currently no memory management and no integration with the garbage collector.
