+This repository contains three kinds of code used in the Vanadium
+project:
+
+1) code which originated outside of Google
+2) code which Google has released as open source
+3) Vanadium code which is derived from code that originated outside of
+   Google, and is therefore still subject to that original code's
+   third-party license
+
+Most of the code under third-party is open source, though some
+packages have restrictive commercial licenses.
