[Users] User level documentation for PITTNull code

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

Hello all,

I was just (due to questions from students whom I had asked to run the PITTNull code for me) looking for documentation on PITTNull's variables in particular precise definitions of News and NewsB as well as (preferably) the other variabels in NullNews' interface.ccl.

Is there any such documentation in the thorns?

I had briefly skimmed through the paper pointed to in the README file but then translating from what the paper uses to what the code uses seems like a risky thing to do to me.

Yours, Roland
