+asdf is Another System Definition Facility for Common Lisp. It intends
+to solve the same class of problems as mk-defsystem - compiling and
+installing Lisp libraries -, but internally it takes advantage of
+modern CL features like pathname support etc., and uses CLOS for
+extensibility.
+
+This package is compiled with SBCL.
