+Copyright F.A.Q.
+
+
+--------------------------------------------------------------
+Q. Our product makes use of the NCBI source code, and we made changes
+   and additions to that version of the NCBI code to better fit it to
+   our needs. Can we copyright the code, and how?
+
+A. You can copyright only the *changes* or the *additions* you made to the
+   NCBI source code. You should identify unambiguously those sections of
+   the code that were modified, e.g. by commenting any changes you made
+   in the code you distribute. Therefore, your license has to make clear
+   to users that your product is a combination of code that is public domain
+   within the U.S. (but may be subject to copyright by the U.S. in foreign
+   countries) and code that has been created or modified by you.
+
+--------------------------------------------------------------
+Q. Can we (re)license all or part of the NCBI source code?
+
+A. No, you cannot license or relicense the source code written by NCBI
+   since you cannot claim any copyright in the software that was developed
+   at NCBI as a 'government work' and consequently is in the public domain
+   within the U.S.
+
+--------------------------------------------------------------
+Q. What if these copyright guidelines are not clear enough or are not
+   applicable to my particular case?

+A. Contact us. Send your questions to 'sra-tools@ncbi.nlm.nih.gov'.
