Usage: $PRG VERSION [NAME]

  Make Isabelle distribution from the master sources at TUM.

  VERSION may be either a tag like "Isabelle2003" that specifies the

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

  current sources as an unofficial release.

  NAME specifies an explicit distribution name, by default it is

  derived from VERSION.

  Checklist for official releases (before running this script):

    * Check Admin/website contents.

    * Check ANNOUNCE, README.html, INSTALL, NEWS, COPYRIGHT, CONTRIBUTORS.

    * Try "isatool makeall all" with Poly/ML, SML/NJ, etc.

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

        cvs -d /usr/proj/isabelle-repository/archive rtag Isabelle2003 isabelle

      PLEASE DO NOT DO THIS UNLESS YOU KNOW WHAT YOU ARE DOING!
