JNAerator (pronounce "generator") simply parses C and Objective-C headers and generates the corresponding JNA and Rococoa Java interfaces (it also has a very limited support for C++).
This lets Java programmers access native libraries transparently, with full IDE support and little to no hand-tweaking.
Users who are looking for ready-to-use libraries should check the NativeLibs4Java project instead.
The newest version!
