[ns] Advice me on TCL HELP

[harish r]

Hi ALL
Can any body direct me where should the definitions of the TCL 
class be present for an adhoc routing protocol.

Is it in the /ns-allinone/ns-2.2x/tcl/mobility or in 
/ns-allinone.ns2.2x/lib/mobilenode.tcl or somewhere else ??

What is the importance of this while making an adhoc protocol to 
work.

Thanks in advance
