[Evolution] How exactly do you do this

I run evo 1.2 and see emails that have signatures like this

GPG Key Available at http://<web.company.com/gpgkeys/me.html
-----BEGIN PGP SIGNATURE-----
Version: GnuPG v1.2.2 (GNU/Linux)

-----END PGP SIGNATURE-----

I use gpg for a number of things and was wondering if there is a howto
to add this to my emails.
