West (Zephyr RTOS Meta-Tool)

West is the Zephyr RTOS project's meta-tool, designed to manage multiple Git repositories under a single directory using a manifest file. It provides commands for initializing workspaces, updating repositories, building, flashing, and debugging Zephyr applications. While primarily a command-line interface tool, `west` also exposes Python APIs for advanced programmatic interaction and extending its functionality. It maintains an active development cycle with frequent releases, often including alpha versions before stable major/minor updates.
