                                  Introduction

   The X.Org Foundation X Window System distribution is a compilation of code
   and documentation from many sources. This document is intended primarily
   as a guide to the licenses used in the distribution: you must check each
   file and/or package for precise redistribution terms. None-the-less, this
   summary may be useful to many users.

   This document is based on the compilation from XFree86. If you find any
   errors or significant omissions in this document, please contact us with
   details at <[9]xorg@lists.freedesktop.org>.

   Most of these licenses are based on the MIT, X Consortium, or BSD
   (original and revised) licenses. All of them are consistent with the
   [10]Open Source Definition, and most are consistent with the Free Software
   Foundation's [11]Free Software Definition.

   While the current licenses are all open source licenses, the X.Org
   Foundation is attempting, over time, to bring as much as possible of the
   code's licenses in the distribution into compliance with the [12]Debian
   Free Software Guidelines.

                            X.Org Preferred License

   The X.Org Foundation has chosen the following format of the MIT License as
   the preferred format for code included in the X Window System
   distribution. This is a slight variant of the common MIT license form
   published by the Open Source Initiative at
   [13]http://www.opensource.org/licenses/mit-license.php.

   Juliusz Chroboczek sorts before Intel Corporation sorts before Daniel
   Stone).
