My oppologies for some of our Avalon disagreements spilling over on
to Cocoon space. The bottom line is this: if you want things to
function as similarly as they have in the past, use Fortress in its
current incarnation. As we work through the disagreements (on the
Avalon Dev group) we will make our decisions public. I designed
Fortress to ease the migration from "Selector" to not needing it.
More on that will be posted on the web page when I write the docs.
