+ (description "Pynac is a derivative of the C++ library GiNaC, which
+allows manipulation of symbolic expressions. It currently provides the
+backend for symbolic expressions in Sage. The main difference between
+Pynac and GiNaC is that Pynac relies on Sage to provide the operations
+on numerical types, while GiNaC depends on CLN for this purpose.")
