+;;; Commentary:
+;;
+;; Org-mode already lets you store/insert links to emacs-lisp files,
+;; just like any other file.  This package lets you precisely link to
+;; any emacs-lisp symbol and access useful information about the symbol.
+;;
+;; Here is the list of available properties when linking from a elisp-symbol:
+;;
+;; :name        The symbol's name.
+;; :stype       The symbol's type (commandp, function, etc.)
+;; :def         The function used to set the symbol's value (defun, etc.)
+;; :keys        The keys associated with the command.
+;; :args        The arguments of the function.
+;; :docstring   The docstring of the symbol.
+;; :doc         The first line of the dostring.
+;; :comment     A comment line just above the sexp, if any.
+;; :fixme       A FIXME comment line just above the sexp, if any.
+;;
+;; Let's say we have a defun like this one:
+;;
+;; ;; FIXME update docstring
+;; (defun org-export-latex-lists ()
+;;   "Convert lists to LaTeX."
+;;   (goto-char (point-min))
+;;   (while (re-search-forward org-export-latex-list-beginning-re nil t)
+;;     (beginning-of-line)
+;;     (insert (org-list-to-latex (org-list-parse-list t)) "\n")))
+;;
+;; And a remember template like:
+;;
+;; (setq org-remember-templates
+;;   '((?s "* DEBUG `%:name' (%:args)\n\n%?\n\nFixme: %:fixme\n  \
+;;          Doc: \"%:doc\"\n\n%a")))
+;;
+;; Then M-x `org-remember' on this sexp will produce this buffer:
+;;
+;; =====================================================================
+;; * DEBUG `org-export-latex-lists' ()
+;;
+;; <== point
+;;
+;; Fixme: update the docstring
+;; Doc: "Convert lists to LaTeX."
+;;
+;; [[file:~/path/file.el::defun%20my-func][Function: my-func]]
