+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.")
