+is a dynamic window manager for X. It manages windows in tiling and floating

 .P
 In tiling mode windows are managed in a master and stacking column. The master

-managed floating, however. In floating mode windows can be resized and moved

-Windows are grouped by tags. All windows with a specific tag can be viewed at a
-time. But each window may contain more than one tag, which makes it visible in
-several views.
+Windows are grouped by tags. Each window can be tagged with one or multiple
