       +.Bd -filled
       +.Nm
       +is a tool for converting farbfeld to vtv.  Each farbfeld image is
       +converted to a single-frame .vtv file. As farbfeld use a 16-bit colour
       +channel while vtv uses only 8 bits, only the most significant 8 bits
       +are considered.
       +.
       +If passed no arguments,
       +.Nm
       +will read a farbfeld image from stdin and produce a vtv on stdout.
       +Otherwise, the arguments must be filenames the form "foo.ff", each of
       +which will be converted to a corresponding "foo.vtv".
       +.
       +If you wish to play the produced .vtv files in
       +.Xr vtv-player 1
       +then the images should all be 73x25 pixels in size.
       +.
       +.Sh LICENSE
       +The vtv-tools are released under the GPLv3 or later.
