# Requires:
#   - GITEA_TOKEN (token with write access) OR credentials usable for basic auth
#     (e.g. the same ones stored in ~/.git-credentials by `git push`)
#   - build artifacts from tools/build_releases.sh (+ optional installer/AppImage)
#
# Usage:
#   GITEA_TOKEN=xxx ./tools/publish_release.sh [version]
#   (version defaults to config/version from project.godot)
