Re: [ns] adding a new protocol

Apart from whatever you have done below, you must also
add the OTcl stubs in .cc to be able to generate and use
Tcl instances.  To give you an example here is how droptail
adds it.

static class DropTailClass : public TclClass {
 public:
        DropTailClass() : TclClass("Queue/DropTail") {}
        TclObject* create(int, const char*const*) {
                return (new DropTail);
        }
} class_drop_tail;

int
DropTail::command(int argc, const char*const* argv) {

        if (argc == 3) {
                if (!strcmp(argv[1], "packetqueue-attach")) {
                        delete q_;
                        if (!(q_ = (PacketQueue*)
TclObject::lookup(argv[2])))
                                return (TCL_ERROR);
                        else {
                                pq_ = q_;
                                return (TCL_OK);
                        }
                }
        }
        return Queue::command(argc, argv);
}

If you have already done the above, can you send the exact
error message occuring when you run your script.
