-;;; Commentary:
-;;
-;; With Avy, you can move point to any position in Emacs – even in a
-;; different window – using very few keystrokes. For this, you look at
-;; the position where you want point to be, invoke Avy, and then enter
-;; the sequence of characters displayed at that position.
-;;
-;; If the position you want to jump to can be determined after only
-;; issuing a single keystroke, point is moved to the desired position
-;; immediately after that keystroke. In case this isn't possible, the
-;; sequence of keystrokes you need to enter is comprised of more than
-;; one character. Avy uses a decision tree where each candidate position
-;; is a leaf and each edge is described by a character which is distinct
-;; per level of the tree. By entering those characters, you navigate the
-;; tree, quickly arriving at the desired candidate position, such that
-;; Avy can move point to it.
-;;
-;; Note that this only makes sense for positions you are able to see
-;; when invoking Avy. These kinds of positions are supported:
-;;
-;; * character positions
-;; * word or subword start positions
-;; * line beginning positions
-;; * link positions
-;; * window positions
-;;
-;; If you're familiar with the popular `ace-jump-mode' package, this
-;; package does all that and more, without the implementation
-;; headache.

+
+;;; Commentary:
+;;
+;; With Avy, you can move point to any position in Emacs – even in a
+;; different window – using very few keystrokes. For this, you look at
+;; the position where you want point to be, invoke Avy, and then enter
+;; the sequence of characters displayed at that position.
+;;
+;; If the position you want to jump to can be determined after only
+;; issuing a single keystroke, point is moved to the desired position
+;; immediately after that keystroke. In case this isn't possible, the
+;; sequence of keystrokes you need to enter is comprised of more than
+;; one character. Avy uses a decision tree where each candidate position
+;; is a leaf and each edge is described by a character which is distinct
+;; per level of the tree. By entering those characters, you navigate the
+;; tree, quickly arriving at the desired candidate position, such that
+;; Avy can move point to it.
+;;
+;; Note that this only makes sense for positions you are able to see
+;; when invoking Avy. These kinds of positions are supported:
+;;
+;; * character positions
+;; * word or subword start positions
+;; * line beginning positions
+;; * link positions
+;; * window positions
+;;
+;; If you're familiar with the popular `ace-jump-mode' package, this
+;; package does all that and more, without the implementation
+;; headache.
