# Unified OBS upload script for dms packages
# Handles Debian and OpenSUSE builds for both x86_64 and aarch64
# Usage: ./distro/scripts/obs-upload.sh [distro] <package-name> [commit-message|rebuild-number]
#
# Examples:
#   ./distro/scripts/obs-upload.sh dms "Update to v1.0.2"
#   ./distro/scripts/obs-upload.sh debian dms
#   ./distro/scripts/obs-upload.sh opensuse dms-git
#   ./distro/scripts/obs-upload.sh debian dms-git 2    # Rebuild with db2 suffix
#   ./distro/scripts/obs-upload.sh dms-git --rebuild=2 # Rebuild with db2 suffix (flag syntax)
