# Creating a new CGAL internal+public release.
#
# Radu Ursu, Sylvain Pion, 2004-2006.

# TODO :
# - Use svn revision instead of separate internal release number ?
# - Cleanup the public/internal separation:
#   - have CGAL_VERSION_NR be not affected by the internal version
#   - have CGAL_REVISION be the revision (replacing the internal number)
# - The public release case should pass the info to create_internal_release.
#   [new] : create_internal_release should not know about internal/public mode.
# - Merge [some parts] into ./create_internal_release ?
