+     "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 @code{read-key} can
+be used.
+
+In order for @code{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,
+such as the positions of characters, words, line beginnings, links, or
+windows.")
