+"Formal Reasoning About Programs" code license information
+<http://adam.chlipala.net/frap/>
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CAUTION: Most of the source files in this distribution are NOT
+open-source in the usual sense.  See the comment at the beginning of
+each source file for its license, which is Creative Commons, oriented
+more toward free distribution of books than the usual collaborative
+model of open-source software.  The author really is trying to keep
+you from remixing your own versions of the book.
+
+However, a few of the library modules used here are sufficiently
+useful that they are released separately under a BSD license, included
+below.  However, the author's advice is: please don't use these
+library modules in real projects.  They are not designed for any use
+beside getting the reader up and running quickly in reading the book,
+sacrificing practicality (and minimal use of axioms) for simplicity.
+
+The following license applies ONLY to the source files:
+Relations.v
+Map.v
+Var.v
+Invariant.v
+ModelCheck.v
+FrapWithoutSets.v
+Sets.v
+Frap.v
+AbstractInterpret.v
+SepCancel.v
