West (Zephyr's meta-tool)
#########################

The Zephyr project includes a swiss-army knife command line tool named
``west``\ [#west-name]_. West is developed in its own `repository`_.  Like
``git`` and ``docker``, the top-level ``west`` command takes some common
options, a sub-command to run, and then options and arguments for that
sub-command::

  west [common-opts] <command> [opts] <args>

West's built-in commands provide a multiple repository management system with
features inspired by Google's Repo tool and Git submodules. West is also
pluggable: you can write your own west "extension commands" which add
additional features to west.  Zephyr provides extension commands for building
applications, debugging them, and more.

You can run ``west --help`` (or ``west -h`` for short) to get top-level help
for available west commands, and ``west <command> -h`` for detailed help on
each command.

The following pages document west's ``v0.5.x`` releases, and provide additional
context about the tool.
