Reconstruct options for restoring mailbox?

[Rosenbaum, Larry M.]

Using Cyrus IMAP 2.3.3 on Solaris 9.

Let's say I'm restoring a subfolder "test" of a mailbox "user.me", and
all I have are the message files.  So here is what the user/me directory
looks like:

-rw-------   1 cyrus    mail        3145 Dec 29 16:02 1.
-rw-------   2 cyrus    mail        3133 Dec 29 16:03 2.
-rw-------   1 cyrus    mail         682 Jan 13 12:38 3.
-rw-------   1 cyrus    mail         688 Jan 13 12:54 4.
-rw-------   1 cyrus    mail         526 Feb 14 10:00 5.
-rw-------   1 cyrus    mail         546 Feb 15 12:38 6.
-rw-------   1 cyrus    mail         672 Feb 27 14:35 7.
-rw-------   1 cyrus    mail        6044 Apr 12 16:44 cyrus.cache
-rw-------   1 cyrus    mail         157 Apr 12 16:44 cyrus.header
-rw-------   1 cyrus    mail         580 Apr 12 16:44 cyrus.index
drwx------   2 cyrus    mail         512 Apr 12 16:41 test

and here is what the user/me/test directory looks like:

-rw-------   1 cyrus    mail       94558 Mar 14 16:22 2.

I need to somehow generate the cyrus.* files in the test subdirectory
and add it to the mailbox database.  What reconstruct command will do
that?  In the old days, a "reconstruct -m" and "reconstruct
user.me.test" would do the job (with a large overhead for the -m
command), but -m is no longer functional.  The -x and -f options look
hopeful, but they won't add the mailbox to the database unless the
cyrus.* files are present.  And "reconstruct user.me.test" or
"reconstruct -r user.me" won't create the cyrus.* files because the
mailbox is not in the mailbox database.  What is the best way to handle
this?

Thanks,
Larry
