Re: GT-ITM Question

Ahmed,

thanks for your reply. I hope Padma's modified sgb2ns becomes available
soon, it would be very helpful. The modified API you propose sounds
great!

While we are waiting for things to happen, can anyone help me with
parsing the GT-ITM output so I can separate transit nodes by hand?

I will send the same question to GT-ITM people and forward any replies
to this list (assuming others are ineterested).

Christos.
