Usage:

    %s "command1" "command2" ...

Each command is of one of the three types:

    [protocol:]commandname?param1=value1&param2=value2&...
    FunctionName?param1=value1&param2=value2&...
    FunctionName(value1,value2,...)

The second and third form are provided for completeness but their use
is not recommended; use gaim-send or gaim-send-async instead.  The
second form uses introspection to find out the parameter names and
their types, therefore it is rather slow.

Examples of commands:

    jabber:goim?screenname=testone@localhost&message=hi
    jabber:gochat?room=TestRoom&server=conference.localhost
    jabber:getinfo?screenname=testone@localhost
    jabber:addbuddy?screenname=my friend

    setstatus?status=away&message=don't disturb
    quit

    GaimAccountFindConnected(,prpl-jabber)
