These two directories are simply variants of the directory just above them.

They have different nib files (different boards), and steal everything else via links to "../XXX."

If you want to create your own board for this version of Ergo, just duplicate one of these directories (preserving all links), double-click on the palette in the directory ../ErgoPalette, and then double-click on the new Ergo.nib file to create/re-arrange your new board.
