         MIG, as maintained by the GNU Hurd developers for the GNU project.

         You need this tool to compile the GNU Mach and GNU Hurd
         distributions, and to compile the GNU C library for the Hurd.  Also,
         you will need it for other software in the GNU system that uses
         Mach-based inter-process communication.
