Oh, I just realized that I misunderstood this. COOKIELIST works as
intended, it just save the cookies, not read them (I mixed the meanings
up), which is why the program "froze", it just awaited input from the
command line.

I still think that the documentation should use "" as the argument value or
it should be stated that using "-" will require input (or CTRL + D).
Thoughts?
