Many of these scripts have been updated.  Some have not.  Please check yours!

This has been done.

All that remains to remove Testing/Data is to merge my topic branch that does it.
Once that happens though there will be some hiccups for all existing clones.
This is because Git does not automatically remove submodules from the work tree
to avoid losing any local commits or configuration.  Therefore everyone will need
to update as follows:

   git checkout master
   rm -rf Testing/Data
   git pull

Any topic branches that have been started based on versions of master before this
merge should be rebased on master after this merge.  Otherwise you will have
problems switching your work tree between versions with the submodule and
versions without it.

I'm not going to perform this merge until we have understanding on the above.
