[ns] Command method

[Andrea Josi <mr_josi@yahoo.it>]

Hi everybody,
i'm reading chapter 3 of NS manual, and i can't
understand the use of the COMMAND method; 
perhaps the reason is that the use of splitObjects is
not clear to me; 

* it seems that the COMMAND method is used when an
OTCL method is called although its only implementation
is in C++, is that correct ?

* if that's correct, then why for example in the
rtProtoDV COMMAND method (in rtProtoDV.cc) there is a
call to the sendpkt method although there are "send"
methods in route-proto.tcl ? 

* has this something to do with the fact that in NS
routing is done in OTCL and packet manipulation in C++
? (again, is that correct ?)

Thanks a lot in advance.
