+The Hurd is also a set of [[servers|translator]] that implement these

The servers run on top of the [[microkernel/Mach]] [[microkernel]] and use
Mach's [[microkernel/mach/IPC]] mechanism to transfer information.

The Hurd supplies the last major software component needed for a complete

M. Stallman (RMS) in 1983. The GNU vision directly drove the creation and has
