# Creating a new CGAL internal/public release.
#
# Radu Ursu, Sylvain Pion, 2004, 2005.

# TODO :
# - The public release case should pass the info to create_internal_release.
# - Merge [some parts] into ./create_internal_release ?
# - What is still missing is to do a checkout of the whole thing
#   so that the Name: CVS keyword is updated in each file.
#   But I'm more and more wondering if we really want that...
# - There should be command line options to set public/internal,
#   and the major/minor/bugfix/version_file release numbers.

# Set the following to "y" in case of public release.
IS_PUBLIC_RELEASE="n"

# Set the major/minor/bugfix release numbers
MAJOR_NUMBER="3"   # 2 digits max
MINOR_NUMBER="2"   # 2 digits max
BUGFIX_NUMBER="0"  # 1 digit  max

# The internal release number is extracted/updated from this file :
VERSION_FILE="version_number"

# Where to put the resulting tarball and where to send the announce.
