+deletion from, the substance or structure of either the Original
+Software or Subject Software, and includes derivative works, as that

+and of itself constitute a Modification.
+G. "Original Software" means the computer software first released

+
+C. The rights granted under Paragraph B. also apply to the combination

+Patents.  It does not apply to any other combinations that include a
+Modification.
+
+D. The rights granted in Paragraphs A. and B. allow the Recipient to
+sublicense those same rights.  Such sublicense must be under the same
+terms and conditions of this Agreement.
+
+3. OBLIGATIONS OF RECIPIENT
+
+A. Distribution or Redistribution of the Subject Software must be made
+under this Agreement except for additions covered under paragraph 3H.
+
+1. Whenever a Recipient distributes or redistributes the Subject
+    Software, a copy of this Agreement must be included with each copy
+    of the Subject Software; and
+2. If Recipient distributes or redistributes the Subject Software in
+    any form other than source code, Recipient must also make the
+    source code freely available, and must provide with each copy of
+    the Subject Software information on how to obtain the source code
+    in a reasonable manner on or through a medium customarily used for
+    software exchange.
+
+B. Each Recipient must ensure that the following copyright notice
+appears prominently in the Subject Software:
+
+Copyright (c) 2006 United States Government as represented by the
+National Aeronautics and Space Administration. No copyright is claimed
+in the United States under Title 17, U.S.Code. All Other Rights Reserved.
+
+C. Each Contributor must characterize its alteration of the Subject
+Software as a Modification and must identify itself as the originator
+of its Modification in a manner that reasonably allows subsequent
+Recipients to identify the originator of the Modification.  In
+fulfillment of these requirements, Contributor must include a file
+(e.g., a change log file) that describes the alterations made and the
+date of the alterations, identifies Contributor as originator of the
+alterations, and consents to characterization of the alterations as a
+Modification, for example, by including a statement that the
+Modification is derived, directly or indirectly, from Original
+Software provided by Government Agency. Once consent is granted, it
+may not thereafter be revoked.
+
+D. A Contributor may add its own copyright notice to the Subject
+Software.  Once a copyright notice has been added to the Subject
+Software, a Recipient may not remove it without the express permission
+of the Contributor who added the notice.
+
+E. A Recipient may not make any representation in the Subject Software
+or in any promotional, advertising or other material that may be
+construed as an endorsement by Government Agency or by any prior
+Recipient of any product or service provided by Recipient, or that may
+seek to obtain commercial advantage by the fact of Government Agency's
+or a prior Recipient's participation in this Agreement.
+
+F. In an effort to track usage and maintain accurate records of the
+Subject Software, each Recipient, upon receipt of the Subject
+Software, is requested to register with Government Agency by visiting
+the following website: https://opensource.gsfc.nasa.gov/.  Recipient's
+name and personal information shall be used for statistical purposes
+only. Once a Recipient makes a Modification available, it is requested
+that the Recipient inform Government Agency at the web site provided
+above how to access the Modification.
+
+G. Each Contributor represents that that its Modification is believed
+to be Contributor's original creation and does not violate any
+existing agreements, regulations, statutes or rules, and further that
+Contributor has sufficient rights to grant the rights conveyed by this
+Agreement.
+
+H. A Recipient may choose to offer, and to charge a fee for, warranty,
+support, indemnity and/or liability obligations to one or more other
+Recipients of the Subject Software.  A Recipient may do so, however,
+only on its own behalf and not on behalf of Government Agency or any
+other Recipient.  Such a Recipient must make it absolutely clear that
+any such warranty, support, indemnity and/or liability obligation is
+offered by that Recipient alone.  Further, such Recipient agrees to
+indemnify Government Agency and every other Recipient for any
+liability incurred by them as a result of warranty, support, indemnity
+and/or liability offered by such Recipient.
+
+I. A Recipient may create a Larger Work by combining Subject Software
+with separate software not governed by the terms of this agreement and
+distribute the Larger Work as a single product. In such case, the
+Recipient must make sure Subject Software, or portions thereof,
+included in the Larger Work is subject to this Agreement.
+
+J. Notwithstanding any provisions contained herein, Recipient is
+hereby put on notice that export of any goods or technical data from
+the United States may require some form of export license from the
+U.S. Government.  Failure to obtain necessary export licenses may
+result in criminal liability under U.S. laws.  Government Agency
+neither represents that a license shall not be required nor that, if
+required, it shall be issued.  Nothing granted herein provides any
+such export license.
+

+
+A. No Warranty: THE SUBJECT SOFTWARE IS PROVIDED "AS IS" WITHOUT ANY

+OTHER APPLICATIONS RESULTING FROM USE OF THE SUBJECT SOFTWARE.
+FURTHER, GOVERNMENT AGENCY DISCLAIMS ALL WARRANTIES AND LIABILITIES
+REGARDING THIRD-PARTY SOFTWARE, IF PRESENT IN THE ORIGINAL SOFTWARE,
