+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.")
