/*
    log messages to console, depending on verbose level

    Use -d to get more verbose output. The more -v you add, the
    more verbose the output becomes.

    Details about the running of the program go to <stderr>.
    Details about scan results go to <stdout>, so that they can easily
    be redirected to a file.
