Sporadic efforts by numerous individuals have been made to keep the information in this wiki current. The hope that the primary development team would make this a canonical source has not been fulfilled. While some of the information and links here are still valid, unfortunately much is not.

      <td valign="top" width="65%"> This web deals with the Mach micro kernel, the base for the Hurd servers which makes out the GNU operating system. This is also the logical place for any other future microkernel, like <a href="http://www.l4ka.org" target="_top">L4</a> for instance. <p> Feel free to add relevant content. </p>
