-;;; Commentary:
-;;
-;; This package provides a generic completion method based on building
-;; a balanced decision tree with each candidate being a leaf. To
-;; traverse the tree from the root to a desired leaf, typically a
-;; sequence of `read-key' can be used.
-;;
-;; In order for `read-key' to make sense, the tree needs to be
-;; visualized appropriately, with a character at each branch node. So
-;; this completion method works only for things that you can see on
-;; your screen, all at once:
-;;
-;; * 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:
+;;
+;; This package provides a generic completion method based on building
+;; a balanced decision tree with each candidate being a leaf. To
+;; traverse the tree from the root to a desired leaf, typically a
+;; sequence of `read-key' can be used.
+;;
+;; In order for `read-key' to make sense, the tree needs to be
+;; visualized appropriately, with a character at each branch node. So
+;; this completion method works only for things that you can see on
+;; your screen, all at once:
+;;
+;; * 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.
