@section fmc-fdelay-status
The program reports the current output status of the forur channels.
It receives no arguments besides the usual @t{-i} or @t{-d}. This
is an example of its current output:
@smallexample
spusa.root# ./tools/fmc-fdelay-status
Channel 1, mode already-triggered, repeat 1
start utc 1470, coarse 124999995, frac 929
end utc 1471, coarse 1249995, frac 929
loop utc 1, coarse 0, frac 0
Channel 2, mode already-triggered, repeat 1
start utc 1507, coarse 124999995, frac 945
end utc 1508, coarse 1, frac 945
loop utc 0, coarse 12, frac 2048
Channel 3, mode already-triggered, repeat 1
start utc 3647, coarse 6362495, frac 949
end utc 3647, coarse 124995, frac 949
