Moving from Mail.app to Mutt

Hello,
I don't know if this forum is still up (last post in 2001 !!) but I will ask anyway.
I installed Mutt on Jaguar, seems to be working fine. I was wondering if somebody did create a small howto for explaining how to move an existing mail base from Mail.app to Mutt.
Thanks. Pierre.

Hello
Sorry for the previous, I just discovered I entered the forum from some Google archive.. So apparently forum is up, and my question still valid ...
Thanks a lot. Pierre.
