Well, first, it's not Net.cc, but NetVar.cc. Are you looking at the
right file? Second, the way it works is that you define a variable in
NetVar.{h,cc} and also in bro.init. Then you can access the variable
from both C++ and bro scripts.

What does the variable represent? I'm curious about why you need an
additional internal variable because they are not needed for most
cases---that's why there are only a limited number of them.
