26 ;;; Commentary:
28 ;; This is a linter for Emacs Lisp. Currently, it mainly catches
29 ;; mispellings and undefined variables, although it can also catch
30 ;; function calls with the wrong number of arguments.
32 ;; Before using, call `elint-initialize' to set up som argument
33 ;; data. This takes a while. Then call elint-current-buffer or
34 ;; elint-defun to lint a buffer or a defun.
36 ;; The linter will try to "include" any require'd libraries to find
37 ;; the variables defined in those. There is a fair amount of voodoo
38 ;; involved in this, but it seems to work in normal situations.
40 ;;; History:
42 ;;; To do:
44 ;; * A list of all standard Emacs variables would be nice to have...
45 ;; * Adding type checking. (Stop that sniggering!)
47 ;;; Code:
