-;;; org-drill.el - Self-testing using spaced repetition
-;;;
-;;; Author: Paul Sexton <eeeickythump@gmail.com>
-;;; Version: 2.3.5
-;;; Repository at http://bitbucket.org/eeeickythump/org-drill/
-;;;
-;;;
-;;; Synopsis
-;;; ========
-;;;
-;;; Uses the SuperMemo spaced repetition algorithms to conduct interactive
-;;; "drill sessions", where the material to be remembered is presented to the
-;;; student in random order. The student rates his or her recall of each item,
-;;; and this information is used to schedule the item for later revision.
-;;;
-;;; Each drill session can be restricted to topics in the current buffer
-;;; (default), one or several files, all agenda files, or a subtree. A single
-;;; topic can also be drilled.
-;;;
-;;; Different "card types" can be defined, which present their information to
-;;; the student in different ways.

-;;; See the file README.org for more detailed documentation.
