+       "Overlord is a build system in Common Lisp.  It is a real build system,
+with all the modern features: rules with multiple outputs, parallel builds,
+immunity to clock issues, and dynamic dependencies.
+
+But Overlord is more than another build system.  Overlord is a uniform
+approach to dependencies inside or outside of a Lisp image.  Overlord is to
+Make what Lisp macros are to C macros.
+
+Overlord is designed to be used from the Lisp REPL.  A command line interface
+is available in a separate repository.  See
+@url{https://github.com/ruricolist/overlord-cli}.")
