+language for applications and as a general purpose programming language.  It
+was originally written to be mostly-compatible with Emacs Lisp, but has
+subsequently diverged markedly.  Its aim is to combine the best features of
+Scheme and Common Lisp and provide an environment that is comfortable for
+implementing both small and large scale systems.")
