-integration with the host operating system, adding documentation, and
-changes to the dynamic linking of libraries.

-A version is not "Substantially Unmodified" if it incorporates
-features not present in a release of Scratch by MIT.  If you do make a
-substantial modification, to avoid confusion with versions of Scratch
-produced by MIT you must remove all Marks from your version of the
-software and refrain from using any of the Marks to refer to your
