   Make Isabelle distribution from the master sources at TUM.

   VERSION may be either a tag like "Isabelle99-XX" that specifies the

   release to be exported from the repository, or "-" to checkout the

   current sources as an unofficial release, or "--" to produce a

   tentative release from the present copy of the Isabelle repository.

   Checklist for official releases (before running this script):

     * Check release name and date in NEWS!

     * Check that README files are up to date (should have Id: lines).

     * Check Admin/index.html.
