     14== `compctl` utility ==
     15The first parameter should be a compositor name, in form it registered to location server, `comp/:0` at this time.
     16Then 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.
     17If you selected viewport you can either list its modes using `l[ist] m[odes]` or set mode using `set {mode number}` arguments.
     18Use mode numbers from viewports list.
     19
     20=== Example ===
     21List viewports in given compositor.
     22{{{
     23/ # compctl comp/:0 l vp
     24id: 27        name: devices/\hw\vesafb\vsl0
     25}}}
     26
     27List viewport modes.
     28{{{
     29/ # compctl comp/:0 vp 27 l m
     30mode 0x111: 640x480
     31mode 0x112: 640x480
     32mode 0x114: 800x600
     33mode 0x117: 1024x768
     34mode 0x115: 800x600
     35mode 0x118: 1024x768
     36mode 0x11a: 1280x1024
     37}}}
