Going from cyrus imap to dovecot

[Gordon Charrick <gordonmc cox net>]

When I convert my main machine from FC1 to FC2 I want to move from using 
cyrus imapd to dovecot. It's mainly for simplicity but I also want to 
use a more standard mail directory format. Unfortunately, I haven't 
found a way to convert my existing mail to maildir format. There seems 
to be lots of information on how to convert to the cyrus format but not 
from it. I really need to keep metainformation like whether or not the 
message has been read already. Has anyone done this?
