[linux-elitists] Procmailise signed mime -> clear (or gpg verification in procmail)

Hey gang,

There's a lot of procmail recipes to turn clear-signed mail into mimey mail,
such as:

  * !^Content-Type: multipart/
  * !^Content-Type: application/pgp
      :0 fBw
      * ^-----BEGIN PGP MESSAGE-----
      * ^-----END PGP MESSAGE-----
      | formail -i "Content-Type: application/pgp; format=text; x-action=encrypt"
      :0 fBw
      * ^-----BEGIN PGP SIGNED MESSAGE-----
      * ^-----BEGIN PGP SIGNATURE-----
      * ^-----END PGP SIGNATURE-----
      | formail -i "Content-Type: application/pgp; format=text; x-action=sign"

However, I want to go the other way, turning mimey signed email into
clearsigned. Doable with something short and sweet in procmail? The aim is
to verify signatures via procmail [1] -> perhaps doing it with mimey
signatures is easier?

Google seems to return a bunch of random gimp's muttrcs for most of my
search terms, which is not what I need. :-)
