west 0.6.3 Zephyr RTOS Project meta-tool
West is the swiss-army knife command line tool of the Zephyr project. Its built-in commands provide a multiple repository management system with features inspired by Google’s Repo tool and Git submodules. West simplifies configuration and is also pluggable: you can write your own west "extension commands" which add additional features to west. Zephyr uses this feature to provide conveniences for building applications, flashing and debugging them, and more.
