Verrazano is a bindings generator targetting Common Lisp. It is designed to have robust support for C and C++ header files, by using GCC-XML as its parser, and to be easily retargettable to a number of different foreign function interfaces. Currently, Verrazano is in development as part of the Google Summer of Code (SoC).
