+            # Viewer.app"). Most of the time, the version manager directs a

+            # with THE SAME name. In that case, everything behaves as usual.
+
+            # The case that was changed is when the version manager offers (or
+            # mandates) an update to a .dmg containing a different app bundle
+            # name. This can happen, for instance, to a user who's downloaded

+            # corresponding Release Candidate viewer -- which will be built as
+            # a release viewer, with app bundle name "Second Life Viewer.app".
+

+            # the embedded install directory name, e.g. Second Life Viewer.
+            # But the Mac installer used to locate the app bundle name in the
