  Usage: dick [<length>] [options]

  Options:

     -b, --big               Change dick format to a bigger one.
     -l, --length [<length>] Set dick length, in characters. Default is 5, a
                             moderate dick length. It must be an integer,
                             positive number (some dignity applies).
     -s, --sperm [<length>]  Display sperm stream with given <length>, in
                             characters. Default is 3. Omit this option or set
                             it to 0 to output no sperm at all.
     -n                      Do not echo trailing newline.
     -v, --version           Display dick version.
     -h, --help              Display this help information.
