Is it possible to specify password in cli?

[Andy Li <andy onthewings net>]

Hi,

I'm using gtk-vnc on a Mac (installed it with homebrew).
It works very well!

Right now, when I connect to a remote screen that requires a password,
it prompts.
I wonder if there is a way to specify the password directly in the cli
when I start it.
I read through `gvncviewer --help-all` but there is nothing regarding
credentials.

Best regards,
Andy
