  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.

    * Tag the current repository version, e.g.:

      PLEASE DON'T DO THIS UNLESS YOU KNOW WHAT YOU'RE DOING!
