# Boost (Custom) Auto-Updater for OBS
# ==============================================================================
#
# 1. Fetches latest version from GitHub releases (boostorg/boost).
# 2. Updates 'Version' and 'Release' in the .spec file.
# 3. Triggers 'osc service manualrun download_files -v' to fetch sources.
# 4. Verifies the downloaded source binary.
# 5. Cleans up old sources.
