Yeah!
I got what Carlos is saying, but still I don't have the time to do it from
the sratch ya. Neither I have the time to build it from sratch and master
tcl for it. Was just fishing for some tcl code, if you can manage it in your
free time it would be great.
Otherwise, will spend a day or two to get that darn thing to work.. which
would be a bit stupid atm.
Cheers!
