+      dwm is a dynamic window manager for X. It manages windows in tiled,

+      dynamically, optimising the environment for the application in use and the
+      task performed.
+      Windows are grouped by tags. Each window can be tagged with one or
+      multiple tags. Selecting certain tags displays all windows with these
+      tags.
