used on each workspace.  Xinerama is fully supported, allowing windows to be
tiled on several screens.")

    (description
     "awesome is a window manager for X.  It manages windows in different
layouts, like floating or tiled.  Any layout can be applied dynamically,
optimizing the environment for the application in use and the task currently
being performed.

In a tiled layout, windows are managed in a master and stacking area.  In a
floating layout windows can be resized and moved freely.  Dialog windows are
always managed as floating, regardless of the layout currently applied.

Windows are grouped by tags in awesome.  Each window can be tagged with one or
more tags.  Selecting certain tags displays all windows with these tags.")
