    For option "--ahl" the <ahl_regexp> should be a Perl regular expression.
    E.g. "--ahl 'ISS... ENMI'" will decode only BUFR SHIP (ISS) from

    might consider setting "--reuse 1" when applying "--ahl", in order to

    bulletins. Such bulletins are very rare nowadays, however, and see also
    the "CAVEAT" for more on this option. Note that the corresponding AHL is
    still extracted (and printed) only once.
