    Setuptools internal actions are organized using a *command design pattern*.
    This means that each action (or group of closely related actions) executed during
    the build should be implemented as a ``Command`` subclass.

    These commands are abstractions and do not necessarily correspond to a command that
    can (or should) be executed via a terminal, in a CLI fashion (although historically
    they would).

    When creating a new command from scratch, custom defined classes **SHOULD** inherit
    from ``setuptools.Command`` and implement a few mandatory methods.
    Between these mandatory methods, are listed:
    :meth:`initialize_options`, :meth:`finalize_options` and :meth:`run`.

    A useful analogy for command classes is to think of them as subroutines with local
    variables called "options".  The options are "declared" in :meth:`initialize_options`
    and "defined" (given their final values, aka "finalized") in :meth:`finalize_options`,
    both of which must be defined by every command class. The "body" of the subroutine,
    (where it does all the work) is the :meth:`run` method.
    Between :meth:`initialize_options` and :meth:`finalize_options`, ``setuptools`` may set
    the values for options/attributes based on user's input (or circumstance),
    which means that the implementation should be careful to not overwrite values in
    :meth:`finalize_options` unless necessary.

    Please note that other commands (or other parts of setuptools) may also overwrite
    the values of the command's options/attributes multiple times during the build
    process.
    Therefore it is important to consistently implement :meth:`initialize_options` and
    :meth:`finalize_options`. For example, all derived attributes (or attributes that
    depend on the value of other attributes) **SHOULD** be recomputed in
    :meth:`finalize_options`.

    When overwriting existing commands, custom defined classes **MUST** abide by the
    same APIs implemented by the original class. They also **SHOULD** inherit from the
    original class.
