        Parameters ::= Parameter | Parameters SP Parameter

        The parameters list, if present, contains a space-separated list of

        key-value pairs, sorted in lexical order by their keyword.  Each

        parameter has its own meaning.

        case-sensitive key-value pairs, sorted in lexical order by

        their keyword. Each parameter has its own meaning.

        later.)

        Commonly used "param" arguments at this point include:

        "CircWindow" -- the default package window that circuits should

        "circwindow" -- the default package window that circuits should

        be established with. It started out at 1000 cells, but some

        research indicates that a lower value would mean fewer cells in

        transit in the network at any given time. Obeyed by Tor 0.2.1.20

        and 0.2.2.10-alpha recognized a "CircPriorityHalflifeMsec" parameter,

        but mishandled it badly.)
