- * This script makes the Sphinx sidebar collapsible and implements intelligent

- *
- * .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).
