fwcamctl: remove, superseded by the video(4) interface
fwcam(4) no longer creates its own character device or implements the
FWCAM_* ioctls; it registers with video(4) and is driven through the
standard V4L2 interface on /dev/videoN.

-.Xr fwcam 4
-driver.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.It Fl f Ar device
-Specify the camera device.
-Defaults to
-.Pa /dev/fwcam0 .
-.El
-.Pp
-The subcommands are:
-.Bl -tag -width indent
-.It Cm info
-Display camera state, current format/mode/framerate, supported formats,
-basic function capabilities, and present features.
-.It Cm snap Op Fl o Ar output.ppm Op Fl s Ar skip
-Capture a single video frame and write it as a PPM image.
-.Pp
-.Bl -tag -width indent -compact
-.It Fl o Ar output.ppm
-Output file path.
-Use
-.Sq -
-for stdout.
-Defaults to
-.Pa snap.ppm .
-.It Fl s Ar skip
-Number of frames to skip before capturing, to allow auto-exposure
-and auto-white-balance to settle.
-Defaults to 5.
-.El
-.Pp
-Supported pixel formats: YUV444, YUV422, YUV411, RGB8, Mono8.
-The frame is converted to RGB24 and written as a binary PPM (P6).
-.It Cm mode Ar format mode rate
-Set the camera video format, mode, and frame rate.
-All arguments are integer indices per the IIDC specification.
-Only Format_0 (VGA) is currently supported by the
-.Xr fwcam 4
-frame assembly path.
-.Pp
-Format_0 modes:
-.Bl -column "Mode" "Resolution" "Pixel format" -compact
-.It Em Mode Ta Em Resolution Ta Em Pixel format
-.It 0 Ta 160x120 Ta YUV444
-.It 1 Ta 320x240 Ta YUV422
-.It 2 Ta 640x480 Ta YUV411
-.It 3 Ta 640x480 Ta YUV422
-.It 4 Ta 640x480 Ta RGB8
-.It 5 Ta 640x480 Ta Mono8
-.El
-.Pp
-Frame rates: 0=1.875 1=3.75 2=7.5 3=15 4=30 5=60 fps.
-.It Cm feat get Ar id
-Query the camera feature with the given numeric ID and display its
-inquiry (presence, on/off, auto, manual, range) and current value.
-.It Cm feat set Ar id value Op Ar value2
-Set the camera feature with the given numeric ID to
-.Ar value .
-For the
-.Sq white_balance
-feature (id 3),
-.Ar value
-is the U/B component and
-.Ar value2
-is the V/R component.
-.El
-.Pp
-Feature IDs:
-.Bl -column "ID" "Name" -compact
-.It Em ID Ta Em Name
-.It 0 Ta brightness
-.It 1 Ta auto_exposure
-.It 2 Ta sharpness
-.It 3 Ta white_balance
-.It 4 Ta hue
-.It 5 Ta saturation
-.It 6 Ta gamma
-.It 7 Ta shutter
-.It 8 Ta gain
-.It 9 Ta iris
-.It 10 Ta focus
-.It 11 Ta temperature
-.It 12 Ta trigger
-.It 13 Ta zoom
-.It 14 Ta pan
-.It 15 Ta tilt
-.El
-.Sh EXAMPLES
-Show camera information:
-.Bd -literal -offset indent
-fwcamctl info
-.Ed
-.Pp
-Capture a photo to
-.Pa photo.ppm ,
-skipping 10 frames for AE to settle:
-.Bd -literal -offset indent
-fwcamctl snap -o photo.ppm -s 10
-.Ed
-.Pp
-Switch to 320x240 YUV422 at 30 fps:
-.Bd -literal -offset indent
-fwcamctl mode 0 1 4
-.Ed
-.Pp
-Read the current gain value:
-.Bd -literal -offset indent
-fwcamctl feat get 8
-.Ed
-.Pp
-Set brightness to 200:
-.Bd -literal -offset indent
-fwcamctl feat set 0 200
