 This is a new package.
 
+This is a re-submission of the first submission. I was asked to
+look over again the authors, license, and copyright information.
+
+In terms of authors and copyright, I have updated the DESCRIPTION
+file with ctb and cph notes for jq, some C code by David Gay, and
+the bison parser.
+
+In terms of license, jq is MIT and other C code included by David Gay
+is also MIT licensed. A dependency in jq, bison, is GPL licensed.
+However, bison has a special exception:
+
+	 As a special exception, you may create a larger work that contains
+   part or all of the Bison parser skeleton and distribute that work
+   under terms of your choice, so long as that work isn't itself a
+   parser generator using the skeleton or a modified version thereof
+   as a parser skeleton.  Alternatively, if you modify or redistribute
+   the parser skeleton itself, you may (at your option) remove this
+   special exception, which will cause the skeleton and the resulting
+   Bison output files to be licensed under the GNU General Public
+   License without this special exception. This special exception was
+   added by the Free Software Foundation in version 2.2 of Bison.
+
+If I understand this correctly, this means we can license this package
+under MIT since this package is not a parser generator itself. The fact
+that jq is licensed under MIT suggests that we can as well. I hope
+I have interpreted this correctly. Please let me know if you disagree.
+
 Note that CHECK says that 'jq' should be sentence cased, but that is
 an improper spelling of the software.
