Of course, this still doesn't solve the problem of making sure that the
_autorebase postinstall script runs whenever the user installs a package
containing DLLs. I wonder if we should reconsider Achim's proposal. If
I understand correctly, it is something like this (oversimplified):
1. Change autorebase.bat to do an incremental rebase instead of trying
to do a full rebase.
2. Arrange for autorebase.bat to never be marked as "done".
Achim, please correct me if my oversimplification distorts your
suggestion too much.
Ken
