About Bro documentation !

Hello Bro's users,

I got a copy of Bro, vp-bro-0-6-alpha_tar, (I don't know is there a newer
version now?), few weeks ago but till now I have time to read it's source
code. Bro is well structured, and if we make a detailed documentation for
it, Bro will be very nice to users and who wants to develop it. So, at
first, I start drawing it's "Class-relations Scheme", which will describes
the relations between Bro's classes. Is there any one did it? If "yes",
please notice me !

PS: Please, fogive my terrible English !
