A copy of PGG has been installed in Gnus for some time, and we have made some changes to it. Are you interested in these patches? I can send the changes as of Gnus 5.10. Two other files is also duplicated between Gnus and FLIM: hex-util.el and sha1-el.el. Only sha1-el.el has been (slightly) modified. I can send that patch too, if you want. Thanks, Simon
