[Dovecot] Question about pre-indexing maildirs

I have a situation with many users and an existing mail delivery agent. Seems like I once saw an imaptest program which I imagine might be used to pre-index maildirs.

For example...

- remember which users and user maildirs have changed since
  last pre-index

- when system quiet pre-index any maildirs which have had
  mail delivered and no access by a mail client (using some
  inotify magic)

If this sounds do-able, let me know where I can find an imaptest version which works with latest dovecot trunk code and the syntax for using it. Seems like I saw this once on the dovecot site.

Thanks.
