Microsoft Reciprocal License (Ms-RL)

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) Reciprocal Grants- For any file you distribute that contains code from
the software (in source code or binary format), you must provide recipients
the source code to that file along with a copy of this license, which license
will govern that file. You may license other files that are entirely your
own work and do not contain code from the software under any terms you choose.

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

(C) 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.

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

(E) 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.

(F) 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". 2015-11-01 22:51:13 -05:00			`- patent-use`
