nekobind is my tool to generate neko bindings to C libraries (currently used mainly for NekoOpenGL. It is changing rapidly whenever i need to wrap a new library, so it can't be regarded as a stable tool. I'm unlikely to really document it well, as use outside of my own laptop is limited. Of course, you can have a look at the source code, and also ask questions on the MailingList if you should be adventurous.

Anyway, for historical reasons: I've completely rewritten nekobind to be more memory-safe, and in fact start the whole binding generation from a haXe interface definition (with some special haxedoc comments). Previously, i've used swig's XML output as a start, but it turned out that starting from a description of the API i'd want to use provides a much more stable and consistent binding.
