#!/usr/bin/env python3
#
# prints a release.properties file for instructing the Maven Release Plugin
# to generate the proper release artefacts without having to manually version
# everything.
#
# Usage:
#
#     build-versions.py <release-version> <dev-version>
#
# This will generate a release.properties file that will release the
# release-version, and will continue development on dev-version. A module
# with a version of its own, such as the experimental modules, is released
# at that version without -SNAPSHOT and continues on the next one.
#
# Example:
#
#    build-versions.py 7.0.0-M1 7.0.0-SNAPSHOT
#
