Is there an archiving utility or other reasonably simple approach
whereby I can process these mail files to (1) considate them into a
single file or archive and (2) eliminate duplicate messages?
I would unpack those files into a Maildir and if you then have
duplicate emails you can remove them with fdupes.
That will find emails that are bit-for-bit identical.
For emails that are the same except for some delivery headers, you
may need to write a script that compares
Message-ID: headers.
