[ns] hwmp.tcl example error

[Mariem Thaalbi]

Hello ,
I installed a patch which supports HWMP under NS2.33. and the installation
was succesfull . But when i try an example which deals with protocol i
obtain error:
invalid command name "Agent/rtProto/HWMP"
    while executing
"Agent/rtProto/HWMP instproc init args {
        $self next $args
}
Thanks for help.
