+
+      It combines the programmable processing of shell scripts and pipes, the
+      interactive visual addressing/programming model of spread sheets, the
+      scenegraph- and interactive controls-, IPC- and client processing- of
+      display servers into one model with zoomable tiling window management.
+
+      It can be used as a standalone desktop of its own, or as a normal
+      application within another desktop as a 'substitute' for your normal
+      terminal emulator.
