[Fedora-music-list] PlanetCCRMA vs. Agnula vs. Fedora Music etc.

Folks, Apropos of this fedora music spin, it would probably be good if someone could clarify how it all fits together, what's (in terms of package sources, websites, etc) deprecated, what's currently relevant, etc. I'm still on the PlanetCCRMA list(s), but I seem to recall Agnula somehow morphing into that, and now I'm just horribly confused about what's what. Even just a reply to this message would allow for it to show up in Google and hence help people who search on the subject. K.
