+
+== `compctl` utility ==
+The first parameter should be a compositor name, in form it registered to location server, `comp/:0` at this time.
+Then you can either list viewports using `l[ist] <vp|viewports>` arguments or select viewport by id (as it listed by listing viewport command), using `<vp|viewport> {numeric id}` to perform viewport-specific operations.
+If you selected viewport you can either list its modes using `l[ist] m[odes]` or set mode using `set {mode number}` arguments.
+Use mode numbers from viewports list.
+
+=== Example ===
+List viewports in given compositor.
+{{{
+/ # compctl comp/:0 l vp
+id: 27        name: devices/\hw\vesafb\vsl0
+}}}
+
+List viewport modes.
+{{{
+/ # compctl comp/:0 vp 27 l m
+mode 0x111: 640x480
+mode 0x112: 640x480
+mode 0x114: 800x600
+mode 0x117: 1024x768
+mode 0x115: 800x600
+mode 0x118: 1024x768
+mode 0x11a: 1280x1024
+}}}
+
+Switch to a different mode.
+{{{
+/ # compctl comp/:0 vp 27 set 0x11a
+}}}
