[Dovecot] Question about installing managesieve

I'm reading http://wiki.dovecot.org/ManageSieve/Install . I already use mercurial queues.

These are the steps I see to install:

hg clone http://hg.dovecot.org/dovecot-1.2 cd dovecot-1.2 hg clone http://hg.rename-it.nl/dovecot-1.2-managesieve-patch .hg/ patches hg qpush

Do the steps change?

Thanks, Jonathan
