This license governs use of the accompanying software. If you use the
software, you accept this license. If you do not accept the license, do not
use the software.

    1. Definitions
       
       The terms "reproduce," "reproduction," "derivative works," and
       "distribution" have the same meaning here as under U.S. copyright law.

       A "contribution" is the original software, or any additions or changes
       to the software.

       A "contributor" is any person that distributes its contribution under
       this license.

       "Licensed patents" are a contributor's patent claims that read directly
       on its contribution.

    2. Grant of Rights
       
       (A) Copyright Grant- Subject to the terms of this license, including
       the license conditions and limitations in section 3, each contributor
       grants you a non-exclusive, worldwide, royalty-free copyright license
       to reproduce its contribution, prepare derivative works of its
       contribution, and distribute its contribution or any derivative works
       that you create.
       
       (B) Patent Grant- Subject to the terms of this license, including the
       license conditions and limitations in section 3, each contributor
       grants you a non-exclusive, worldwide, royalty-free license under its
       licensed patents to make, have made, use, sell, offer for sale, import,
       and/or otherwise dispose of its contribution in the software or
       derivative works of the contribution in the software.

    3. Conditions and Limitations

       (A) No Trademark License- This license does not grant you rights to use
       any contributors' name, logo, or trademarks.

       (B) If you bring a patent claim against any contributor over patents
       that you claim are infringed by the software, your patent license from
       such contributor to the software ends automatically.

       (C) If you distribute any portion of the software, you must retain all
       copyright, patent, trademark, and attribution notices that are present
       in the software.

       (D) If you distribute any portion of the software in source code form,
       you may do so only under this license by including a complete copy of
       this license with your distribution. If you distribute any portion of
       the software in compiled or object code form, you may only do so under
       a license that complies with this license.

       (E) The software is licensed "as-is." You bear the risk of using it.
       The contributors give no express warranties, guarantees, or conditions.
       You may have additional consumer rights under your local laws which
       this license cannot change. To the extent permitted under your local
       laws, the contributors exclude the implied warranties of
       merchantability, fitness for a particular purpose and non-infringement.
