+ * sidebar.js
+ * ~~~~~~~~~~
+ *
+ * This script makes the Sphinx sidebar collapsible.
+ *
+ * .sphinxsidebar contains .sphinxsidebarwrapper. This script adds
+ * in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton
+ * used to collapse and expand the sidebar.
+ *
+ * When the sidebar is collapsed the .sphinxsidebarwrapper is hidden
+ * and the width of the sidebar and the margin-left of the document
+ * are decreased. When the sidebar is expanded the opposite happens.
+ * This script saves a per-browser/per-session cookie used to
+ * remember the position of the sidebar among the pages.
+ * Once the browser is closed the cookie is deleted and the position
+ * reset to the default (expanded).
+ *
+ * :copyright: Copyright 2007-2011 by the Sphinx team, see AUTHORS.
+ * :license: BSD, see LICENSE for details.
