But I'm using this to test what it generated. Not what it received. If
you don't trust your own keys than what should you trust ;)

I'm going to use gpg to generate your own key, then run this to test if
it worked.

I guess I could add an option to verify before you send if you are
paranoid.

quilt mail --send --sign --verify ...

Without --verify, it can use gpg to still make sure the key works, with
--verify it would use gpgv.

Oh this reminds me. I need to change --pass to --sign.
