prowatch.sh help page

    Watch and listen to stuff that is currently uploaded to Volafile with
    Volfile Pro™ speeds.
    Every argument that is not prepended with any option will be treated as
    link to media hosted on vola. You can still use this script as non-pro
    user but you will get usual download speeds which may result in longer
    buffering.

-h, --help
    Show this help message.

-n, --nick <name>
    Specify your login name.

-p, --pass <password>
    Set your password.
