    If I recall correctly, cflowd requires arts++ to run, so if you have arts++
    installed, you can use artsportagg, thusly:

    % man artsportagg

    artsportagg(l) artsportagg(l)

    NAME
           artsportagg - utility to aggregate port table objects in
           time domain

    SYNOPSIS
           artsportagg [-h hours] [-o] [-q] outfile infile(s)

    DESCRIPTION
           artsportagg is a utility that reads port table objects
           from ARTS files (infile(s)) and aggregates them in the
           time domain, placing the resulting port table object(s)
           into an output file (outfile).

    OPTIONS
           -h hours
                  The -h hours option may be used to specify the
                  period of aggregation, in hours. The hours argu-
                  ment accepts a decimal value to permit aggregation
                  by fractional hour values. When the -h hours
                  option is not used, artsportagg will write a single
                  port table object for the entire time interval seen
                  in infile(s) to outfile.

           -o By default, artsportagg appends to the output file,
                  so you may accumlate aggregate port table objects
                  in a single file over multiple invocations of art-
                  sportagg. You may override this behavior with the
                  -o option. This will cause artsportagg to over-
                  write the output file instead of appending to it.

           -q By default, artsportagg prints a '.' for each port
                  table object it reads and prints a '+' for each
                  object it writes. You may suppress this behavior
                  with the -q (quiet) option.

    EXAMPLES
           artsportagg -h 1.0 /tmp/portagg1hr.19980821 arts.19980821
