Thanks, I actually already used it on his series :)

What's the use of 'aiai-concat-mboxes' over a simple 'cat'? Just 
inserting the extra blank line, I guess? But if I have a concatenated 
mailbox, this is better:

./verify ../l2-mtd/ gpmi-name < ~/tmp/huang.mbox

One issue (possibly related to the above question?) was that aiaia 
complained (via checkpatch.pl) about no sign-offs when I processed using 
the input redirection method on a multi-message mbox. I can take a 
closer look next time, but it's not a big deal, since I can verify this 
pretty easily.

Thanks again for the help and for the nice tools.
