=head1 copy-mailbox.pl

Copy mail from one location to another, perhaps converting formats.

The source mail is specified with the C<--source> flag, and the destination
with the C<--dest> parameter. Both must be followed by a full path, which
can end with a / to indicate that it is in Maildir format.

By default email is just coped, but the C<--delete> flag can be given to
have it moved instead.
