Microsoft Public License (Ms-PL)

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.

rename/order license properties better reflect how licenses work and are structured grant (permissions) conditioned on (conditions) with limitations Permissions coming first combats mistaken but apparently widespread impression that licenses impose conditions, even such that without a license, there would be no conditions/work would be in the public domain. Requirements->Conditions emphasizes that they are pertinent if one wants to take advantage of permissions. Forbiddens->Limitations is more accurate: in most cases licenses don't give permission to hold licensors liable, in some cases to use licensors' trademarks or patents, but a licensee does not lose the permissions granted by the license if the licensee holds licensor liable, etc. Also emphasizes that there are limitatations on the license grant, not that the license imposes prohibitions. The most concise place to see both the rename and reorder is in _includes/license-overview.html I did not reorder the appearance of the groups of properties in license source files (.txt files in _licenses) as those orderings are not used to render anything on the webiste.

Rename "Patent Grant" to "Patent Use" Per the discussion in #168, the consumers of the softare are granted the right to use patents. So "Patent Use" makes more sense from a consumer perspective than "Patent Grant". 2015-11-02 04:51:13 +01:00			`- patent-use`
