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.

There is a newer version: 0.12
