-OSKit-Mach began as a branch of the GNUMach 1.2 kernel, but since the release of GNU Mach 1.3, OSKit-Mach has been merged as the new GNUMach 2.x mainline. The [[Mach/MachHistory]] page tells a more interesting story including other operating systems who use Mach in their kernels.
+OSKit-Mach began as a branch of the GNUMach 1.2 kernel, but since the release of GNU Mach 1.3, OSKit-Mach has been merged as the new GNUMach 2.x mainline. The [[history]] page tells a more interesting story including other operating systems who use Mach in their kernels.
 
 GNU Mach 2.0 makes use of the drivers provided by [the OSKit](http://www.cs.utah.edu/flux/oskit/) from [the Flux Research Group](http://www.cs.utah.edu/flux/). The OSKit provided a neat driver base where both [[TWiki/FreeBSD]] and Linux (2.2.12) drivers are made available to [Mach](http://www-2.cs.cmu.edu/afs/cs/project/mach/public/www/mach.html) and thus the Hurd. However, OSKit isn't maintained anymore.
 
 ## <a name="Status"> Status </a>
 
-The OSKit-Mach version of GNUmach is today (2005) more or less defunct. Nobody is working on it. Few people ever got it running, and by now there are also problems building with recent toolchains. Instead, the Hurd developers now concentrate on completely different microkernels (Coyotos being the current favourite), as well as on improving the original GNU Mach 1.x codebase. (See also [[GNUMachRevivalProject]].)

-MIG is the Mach 3.0 interface generator, as maintained by the GNU Hurd developers for the GNU project.
-
-The interface generator produces stub code from interface definition (.defs) files. The stub code makes it easy to implement and use Mach interfaces as remote procedure calls (RPC).
-
-You need this tool to compile the GNU Mach and Hurd distributions, and to compile the GNU C library for the Hurd. Also, you will need it for other software in the GNU systems that uses Mach-based inter-process communication.

-## <a name="Status_of_the_project"> Status of the project </a>
-
-MIG 1.3 was released in March 2002, and features compatibility with OSF Mach.
