gpg signatures

[hymie]

Back story -- I'm an old fogey who hates change.

When I use mhshow to view a message that is GPG-signed, I end up with
an error at the end:

mhshow: don't know how to display content
    (content application/pgp-signature in message 60748, part 1.2)

So I have my own script that will take apart a message, pull out the
signature, and verify it.

But I assume there's a "correct" way to do it?
