#!/bin/bash
#
# Draft release generator.
# This utility is responsible for submitting a draft release to github repo
# It is agnostic of other processes, when executed it will draft a release,
# based on the most recent reachable tag.
#
# Requirements:
#   - GITHUB_TOKEN variable set with GitHub token. Access level: repo.public_repo
#   - artifacts directory in place
#     - The directory is created by create_artifacts.sh mechanism
#     - The artifacts need to be created with the same tag, obviously
