;;; Commentary:
;; This is yet another implementation to allow the annotation of a
;; file without modification of the file itself. The annotation is in
;; org syntax so you can use all of the org features you are used to.
;; To use you might put the following in your .emacs:
;;
;; (require 'org-annotate-file)
;; (global-set-key (kbd "C-c C-l") 'org-annotate-file) ; for example
;;
;; To change the location of the annotation file:
;;
;; (setq org-annotate-file-storage-file "~/annotated.org")
;;
;; Then when you visit any file and hit C-c C-l you will find yourself
;; in an org buffer on a headline which links to the file you were
;; visiting, e.g:
;; * ~/org-annotate-file.el
;; Under here you can put anything you like, save the file
;; and next time you hit C-c C-l you will hit those notes again.
;;
;; To put a subheading with a text search for the current line set
;; `org-annotate-file-add-search` to non-nil value. Then when you hit
;; C-c C-l (on the above line for example) you will get:
;; * ~/org-annotate-file.el
;; ** `org-annotate-file-add-search` to non-nil value. Then whe...
;; Note that both of the above will be links.
;;; Code:
