gpg2, gpg-agent, enigmail

A 'yum upgrade' on Fedora 13 brought in gpg2 instead of the original gpg. It is "more suited for server and embedded platforms... and more targeted to the desktop", as per the man page. Fedora is now also providing Thunderbird 3.1.3 which works nicely with enigmail 1.2.2, provided that you invoke gpg-agent.
