+           License For Customer Use of NVIDIA Software
+
+
+IMPORTANT NOTICE -- READ CAREFULLY: This License For Customer Use of
+NVIDIA Software ("LICENSE") is the agreement which governs use of
+the software of NVIDIA Corporation and its subsidiaries ("NVIDIA")
+downloadable herefrom, including computer software and associated
+printed materials ("SOFTWARE").  By downloading, installing, copying,
+or otherwise using the SOFTWARE, you agree to be bound by the terms
+of this LICENSE.  If you do not agree to the terms of this LICENSE,
+do not download the SOFTWARE.
+
+RECITALS
+
+Use of NVIDIA's products requires three elements: the SOFTWARE, the
+hardware, and a personal computer. The SOFTWARE is protected by copyright
+laws and international copyright treaties, as well as other intellectual
+property laws and treaties.  The SOFTWARE may be protected by various
+patents, and is not sold, and instead is only licensed for use, strictly
+in accordance with this document.  The hardware is protected by various
+patents, and is sold, but this agreement does not cover that sale, since
+it may not necessarily be sold as a package with the SOFTWARE.  This
+agreement sets forth the terms and conditions of the SOFTWARE LICENSE only.
+
+1.  DEFINITIONS
+
+1.1  Customer.  Customer means the entity or individual that
+downloads or otherwise obtains the SOFTWARE.
+
+2.  GRANT OF LICENSE
+
+2.1  Rights and Limitations of Grant.  NVIDIA hereby grants Customer
+the following non-exclusive, non-transferable right to use the
+SOFTWARE, with the following limitations:
+
+2.1.1  Rights.  Customer may install and use multiple copies of the
+SOFTWARE on a shared computer or concurrently on different computers,
+and make multiple back-up copies of the SOFTWARE, solely for Customer's
+use within Customer's Enterprise. "Enterprise" shall mean individual use
+by Customer or any legal entity (such as a corporation or university)
+and the subsidiaries it owns by more than fifty percent (50%).
+
+2.1.2  Open Source Exception.  Notwithstanding the foregoing terms
+of Section 2.1.1, SOFTWARE may be copied and redistributed solely for
+use on operating systems distributed under the terms of an OSI-approved
+open source license as listed by the Open Source Initiative at
+http://opensource.org, provided that the binary files thereof are not
+modified, and Customer provides a copy of this license with the SOFTWARE.
+
+2.1.3  Limitations.
+
+No Reverse Engineering.  Customer may not reverse engineer,
+decompile, or disassemble the SOFTWARE, nor attempt in any other
+manner to obtain the source code.
+
+Usage. SOFTWARE is licensed only for use with microprocessor(s) which have
+been (i) designed by NVIDIA and (ii) either (a) sold by or (b) licensed by
+NVIDIA. Customer shall not use SOFTWARE in conjunction with, nor cause
+SOFTWARE to be executed by, any other microprocessor.
+
+No Translation. Customer shall not translate SOFTWARE, nor cause or permit
+SOFTWARE to be translated, from the architecture or language in which it is
+originally provided by NVIDIA, into any other architecture or language.
+
+No Rental.  Customer may not rent or lease the SOFTWARE to someone
+else.
+
+3.  TERMINATION
+
+This LICENSE will automatically terminate if Customer fails to
+comply with any of the terms and conditions hereof.  In such event,
+Customer must destroy all copies of the SOFTWARE and all of its
+component parts.
+
+Defensive Suspension.  If Customer commences or participates in any legal
+proceeding against NVIDIA, then NVIDIA may, in its sole discretion,
+suspend or terminate all license grants and any other rights provided
+under this LICENSE during the pendency of such legal proceedings.
+
+4.  COPYRIGHT
+
+All title and copyrights in and to the SOFTWARE (including but
+not limited to all images, photographs, animations, video, audio,
+music, text, and other information incorporated into the SOFTWARE),
+the accompanying printed materials, and any copies of the SOFTWARE,
+are owned by NVIDIA, or its suppliers.  The SOFTWARE is protected
+by copyright laws and international treaty provisions.  Accordingly,
+Customer is required to treat the SOFTWARE like any other copyrighted
+material, except as otherwise allowed pursuant to this LICENSE
+and that it may make one copy of the SOFTWARE solely for backup or
+archive purposes.
+
+5.  APPLICABLE LAW
+
+This agreement shall be deemed to have been made in, and shall be
+construed pursuant to, the laws of the State of California.
+
+6.  DISCLAIMER OF WARRANTIES AND LIMITATION ON LIABILITY
+
+6.1  No Warranties.  TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE
+LAW, THE SOFTWARE IS PROVIDED "AS IS" AND NVIDIA AND ITS SUPPLIERS
+DISCLAIM ALL WARRANTIES, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT
+NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
+FOR A PARTICULAR PURPOSE.
+
+6.2  No Liability for Consequential Damages.  TO THE MAXIMUM
+EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL NVIDIA OR
+ITS SUPPLIERS BE LIABLE FOR ANY SPECIAL, INCIDENTAL, INDIRECT, OR
+CONSEQUENTIAL DAMAGES WHATSOEVER (INCLUDING, WITHOUT LIMITATION,
+DAMAGES FOR LOSS OF BUSINESS PROFITS, BUSINESS INTERRUPTION, LOSS
+OF BUSINESS INFORMATION, OR ANY OTHER PECUNIARY LOSS) ARISING OUT
+OF THE USE OF OR INABILITY TO USE THE SOFTWARE, EVEN IF NVIDIA HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7.  MISCELLANEOUS
+
+The United Nations Convention on Contracts for the International
+Sale of Goods is specifically disclaimed.  If any provision of this
+LICENSE is inconsistent with, or cannot be fully enforced under,
+the law, such provision will be construed as limited to the extent
+necessary to be consistent with and fully enforceable under the law.
+This agreement is the final, complete and exclusive agreement between
+the parties relating to the subject matter hereof, and supersedes
+all prior or contemporaneous understandings and agreements relating
+to such subject matter, whether oral or written.  Customer agrees
+that it will not ship, transfer or export the SOFTWARE into any
+country, or use the SOFTWARE in any manner, prohibited by the
+United States Bureau of Export Administration or any export laws,
+restrictions or regulations.  This LICENSE may only be modified in
+writing signed by an authorized officer of NVIDIA.
