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.
