libogg++java is a Java native interface to libogg++. It provides C++ and Java wrappers, as well as Java classes. It also provides control files to generate them from the libogg++ interface using SWIG. The major and minor versions of this JNI will track that of libogg++, but its bugfixes are independent of libogg++ bugfixes.
GNU Mach is the microkernel upon which a GNU Hurd system is based. It provides an Inter Process Communication (IPC) mechanism which the Hurd uses to define interfaces for implementing in a distributed multi-server fashion the services a traditional operating system kernel provides. Mach is particularly well-suited for SMP and network cluster techniques. Thread support is provided at the kernel level, and the kernel itself takes advantage of that. Network transparency at the IPC level makes resources of the system available across machine boundaries.
