+windows managers such as Awesome and XMonad.  @code{perspective.el} provides
+multiple workspaces (or \"perspectives\") for each Emacs frame.  Each
+perspective is composed of a window configuration and a set of buffers.
+Switching to a perspective activates its window configuration, and when in a
+perspective only its buffers are available by default.")
