[Dovecot] convert_mail ?

[Andrew Z]

I can't find much documentation on the convert_mail plugin.  For 
example, on the wiki plugins page, clicking on convert goes to 
<http://wiki.dovecot.org/InterWiki> which is not relevant.

Can I use convert_mail to migrate from UW IMAP 2002  mbox format where 
some mail is in ~/ and the inboxes are in /var/spool/mail?  Will it know 
which files are mbox folders, so it doesn't try to convert other files 
in the home directories?  When are the e-mails converted?  Are the old 
files deleted?   Is this configuration snippet valid? 

default_mail_env = maildir:~/Maildir
convert_mail = mbox:~/:INBOX=/var/mail/%u

If I can do that, it seems like an easy change.
