Locking and Mail::Box::Manager

Hi,

I've read about Mail::Box::Locker[0] and on this page the synopsis is:

   use Mail::Box;
   my $folder =3D Mail::Box->new(lock_method =3D> 'DOTLOCK');
   print $folder->locker->type;


On [1] it is written that the Mail::Box::Manager creates Mail::Box
objects. How can I specify the locking method when I use
Mail::Box::Manager? Locking is not mentioned on [1].

example:
    my $manager =3D Mail::Box::Manager->new;
    my $mailbox =3D $manager->open("$mailboxname", access =3D> 'rw', type
=3D> 'mbox', create =3D> 1);


Is it sufficient to write

    my $mailbox =3D $manager->open("$mailboxname", access =3D> 'rw', type
=3D> 'mbox', create =3D> 1, lock_method =3D> 'DOTLOCK');

Thanks for your help,
James
