[ns] a warning

[Yan Yu <yanyu@catarina.usc.edu>]

HI, there,
  when I run the simulation , I got the warning msg:

warning: no class variable Snoop::debug_

	see tcl-object.tcl in tclcl for info about this warning.


Does it matter? does it mean there is no debug method is defined in Snoop
class?  I could not find out where it try to call Snoop::debug_  though.
I have looked at tcl/ex/snoop/snoop.tcl; util.tcl, and  snoop.cc(h) under
ns main directory,  but could NOT find a place calling debug.. so it kind
of wired to me..

DOes anyone have clue about it? DOes this warning matter?

Thanks in advance!
