+user-defined function when exiting Common Lisp (both @code{quit} from the REPL
+or a kill in a shell).  Like @code{atexit} in C and Python or Java’s
+@code{Runtime.addShutdownHook()}.  It currently supports SBCL, CCL, ECL, ABCL,
+Allegro CL, clisp and CMUCL.  Before exit-hooks, there was no portable way of
+doing so and no staightforward way to use an exit hook on ABCL.  It can be used
+for tasks like parmenantly save something when exiting Lisp.")
