Removing messages from one of multiple archives

[Ed Reiss <ereiss@webwillow.com>]

I've been handed over the process of creating and managing two mailman mailing lists
that use Mhonarc as a web archive tool. I need to remove some archived test messages
I've been sending to the mailing lists and I found reference to the RMM command
in the mhonarc docs online at: 

http://www.mhonarc.org/MHonArc/doc/resources/rmm.html

Since I'm managing two archives I noticed that the command docs don't mention how 
one specifies the archive from which the messages should be removed. Can someone 
clarify the format of the command when there are several archives, and the specified
messages should be removed from only one of them?

Thanks for your help,
