            6 .Nd determines flux from profile of shear velocities
            7 .Sh SYNOPSIS

            9 .Op Ar file ...
           10 .Sh DESCRIPTION
           11 The
           12 .Nm
           13 utility outputs the cumulative sediment shear flux from a profile
           14 of positions and shear velocities.
           15 .Nm
           16 expects that the first column of input is a list of positions, and
           17 the second column is a list of shear velocities.
           18 All other columns are discarded.
           19 Input can be supplied through stdin or from a single file.
           20 .Pp
           21 The output is the cumulative sediment flux with units square meters
           22 per second (m^2/s).
           23 .Sh EXIT STATUS
           24 .Nm
           25 exits 0 on success, and >0 if a runtime error occurs:
