+;;; Commentary:
+
+;; Org Link Edit provides Paredit-inspired slurping and barfing
+;; commands for Org link descriptions.
+;;
+;; There are four commands, all which operate when point is on an Org
+;; link.
+;;
+;; - org-link-edit-forward-slurp-word
+;; - org-link-edit-backward-slurp-word
+;; - org-link-edit-forward-barf-word
+;; - org-link-edit-backward-barf-word
+;;
+;; Org Link Edit doesn't bind these commands to any keys. Finding
+;; good keys for these commands is difficult because, while it's
+;; convenient to be able to quickly repeat these commands, they won't
+;; be used frequently enough to be worthy of a short, repeat-friendly
+;; binding. Using Hydra [1] provides a nice solution to this. After
+;; an initial key sequence, any of the commands will be repeatable
+;; with a single key. (Plus, you get a nice interface that reminds
+;; you of the keys). Below is one example of how you could configure
+;; this.
+;;
+;; (define-key org-mode-map YOUR-KEY
