  24 ;;; Commentary:
  25 ;;
  26 ;; EDE is the top level Lisp interface to a project management scheme
  27 ;; for Emacs.  Emacs does many things well, including editing,
  28 ;; building, and debugging.  Folks migrating from other IDEs don't
  29 ;; seem to think this qualifies, however, because they still have to
  30 ;; write the makefiles, and specify parameters to programs.
  31 ;;
  32 ;; This EDE mode will attempt to link these diverse programs together
  33 ;; into a comprehensive single interface, instead of a bunch of
  34 ;; different ones.
  35
  36 ;;; Install
  37 ;;
  38 ;;  This command enables project mode on all files.
