;;; Commentary:
;; SLIME is the ``Superior Lisp Interaction Mode for Emacs.''
;;
;; SLIME extends Emacs with support for interactive programming in
;; Common Lisp. The features are centered around slime-mode, an Emacs
;; minor-mode that complements the standard lisp-mode. While lisp-mode
;; supports editing Lisp source files, slime-mode adds support for
;; interacting with a running Common Lisp process for compilation,
;; debugging, documentation lookup, and so on.
;;
;; The slime-mode programming environment follows the example of
;; Emacs's native Emacs Lisp environment. We have also included good
;; ideas from similar systems (such as ILISP) and some new ideas of
;; our own.
;;
;; SLIME is constructed from two parts: a user-interface written in
;; Emacs Lisp, and a supporting server program written in Common
;; Lisp. The two sides are connected together with a socket and
;; communicate using an RPC-like protocol.
;;
;; The Lisp server is primarily written in portable Common Lisp. The
;; required implementation-specific functionality is specified by a
;; well-defined interface and implemented separately for each Lisp
;; implementation. This makes SLIME readily portable.
