+License:
+This license governs use of code marked as “sample” or “example” available on
+this web site without a license agreement, as provided under the section above
+titled “NOTICE SPECIFIC TO SOFTWARE AVAILABLE ON THIS WEB SITE.” If you use
+such code (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.
+
+(F) Platform Limitation - The licenses granted in sections 2(A) and 2(B)
+extend only to the software or derivative works that you create that run on a
+Microsoft Windows operating system product.
