Shared Source License for IronPython

This license governs use of the accompanying software (“Software”), and your use of the Software constitutes acceptance of this license.

You may use the Software for any commercial or noncommercial purpose, including distributing derivative works.

In return, we simply require that you agree:
1.	Not to remove any copyright or other notices from the Software. 
2.	That if you distribute the Software in source code form you do so only under this license (i.e. you must include a complete copy of this license with your distribution), and if you distribute the Software solely in object form you only do so under a license that complies with this license. 
3.	That the Software comes "as is", with no warranties. None whatsoever. This means no express, implied or statutory warranty, including without limitation, warranties of merchantability or fitness for a particular purpose or any warranty of title or non-infringement. Also, you must pass this disclaimer on whenever you distribute the Software or derivative works. 
4.	That neither Microsoft nor any contributor to the Software will be liable for any of those types of damages known as indirect, special, consequential, or incidental related to the Software or this license, to the maximum extent the law permits, no matter what legal theory it’s based on. Also, you must pass this limitation of liability on whenever you distribute the Software or derivative works. 
5.	That if you sue anyone over patents that you think may apply to the Software for a person's use of the Software, your license to the Software ends automatically. 
6.	That the patent rights, if any, granted in this license only apply to the Software, not to any derivative works you make.
7.	That if you are an agency of the U.S. Government, (i) Software provided pursuant to a solicitation issued on or after December 1, 1995, is provided with the commercial license rights set forth in this license, and (ii) Software provided pursuant to a solicitation issued prior to December 1, 1995, is provided with “Restricted Rights” as set forth in FAR, 48 C.F.R. 52.227-14 (June 1987) or DFAR, 48 C.F.R. 252.227-7013 (Oct 1988), as applicable.

Read below for answers to frequently asked questions about this license.

Q: Is this license OSI compliant?
A: This license has not been submitted to OSI, but it allows developers to take full advantage of a dynamic language on the CLR and to have the freedom to distribute their works for the benefit of the community at large. The license is half of a page long and very straight forward. We believe it stands up to what developers demand of an "open" license.

Q: What copyright rights does the license grant me?
A: The license grants you a copyright license to make unlimited copies of the Software in source or object code form, as well as to create Derivative Works (as that term is defined under US copyright law). This means that in addition to making unlimited copies of the Software, you have a copyright license to modify the Software and to use all or part of the Software to create a Derivative Work.

Q: What patent rights does the license grant me?
A: This license grants you a patent license to use and distribute the Software under any Microsoft patent claims that read on the Software itself. In other words, if you create a modified version of the Software, you still retain the patent license to use and distribute the original portions of the Software under the specific Microsoft patent claims that read on the Software, but you do not have a patent license as to the new functionality you may have added by modifying the Software. This result is typical of many common open source licenses, including the Common Public License (CPL) and the Mozilla Public License (MPL). In addition, this license grants no rights to any Microsoft patents that read on other components or files not included in the Software. This means that no patent license is granted to use or distribute any other software or technology that may be needed to use the Software or was created from the Software (for example, any compiled output of the Software, the combination of the Software with other hardware or other software, or any additional enabling technologies that may be necessary to make or use the Software or any final product that includes the Software).
