    // According to style(9),  it is not a good practice to call exit(3) with
    // arbitrary values to indicate a failure condition when ending a program.
    // Instead, the pre-defined exit codes from sysexits should be used, so the
    // caller of the process can get a rough estimation about the failure class
    // without looking up the source code.
    // EX_USAGE (64)        The command was used incorrectly, e.g., with the
    //                      wrong number of arguments, a bad flag, a bad syntax
    //                      in a parameter, or whatever.
    // EX_UNAVAILABLE (69)  A service is unavailable.  This can occur if a sup­
    //                      port program or file does not exist.  This can also
    //                      be used as a catchall message when something you
    //                      wanted to do doesn't work, but you don't know why.
