;;; ILISP is already set up with support for a number of dialects.
;;; Each dialect has a command NAME that will start an inferior LISP
;;; of that dialect.  NAME-hook is a hook that will run after the
;;; default settings for NAME are set up.  NAME-program is the default
;;; program for NAME. A prefix when starting a dialect will cause you
;;; to be prompted for the buffer name and the program.  When setting
;;; something in a hook, you should use the most general dialect that
;;; makes sense. Dialect definitions and their hooks are executed from
;;; least specific to most specific.  They will be executed before the
;;; inferior LISP is started.
;;; These are the currently supported dialects.  The dialects
;;; are listed so that the indentation corresponds to the hierarchical
;;; relationship between dialects.

;;; you only need to change the variables that are different than in
;;; the parent dialect.
