+ """In order to support editable installations (see :pep:`660`) all
+ build subcommands **SHOULD** implement this protocol. They also **MUST** inherit
+ from ``setuptools.Command``.
+
+ When creating an :pep:`editable wheel <660>`, ``setuptools`` will try to evaluate
+ custom ``build`` subcommands using the following procedure:
+
+ 1. ``setuptools`` will set the ``editable_mode`` attribute to ``True``
+ 2. ``setuptools`` will execute the ``run()`` command.
+
+ .. important::
+ Subcommands **SHOULD** take advantage of ``editable_mode=True`` to adequate
+ its behaviour or perform optimisations.
+
+ For example, if a subcommand don't need to generate any extra file and
+ everything it does is to copy a source file into the build directory,
+ ``run()`` **SHOULD** simply "early return".
+
+ Similarly, if the subcommand creates files that would be placed alongside
+ Python files in the final distribution, during an editable install
+ the command **SHOULD** generate these files "in place" (i.e. write them to
+ the original source directory, instead of using the build directory).
+ Note that ``get_output_mapping()`` should reflect that and include mappings
+ for "in place" builds accordingly.
+
+ 3. ``setuptools`` use any knowledge it can derive from the return values of
+ ``get_outputs()`` and ``get_output_mapping()`` to create an editable wheel.
+ When relevant ``setuptools`` **MAY** attempt to use file links based on the value
+ of ``get_output_mapping()``. Alternatively, ``setuptools`` **MAY** attempt to use
+ :doc:`import hooks <python:reference/import>` to redirect any attempt to import
+ to the directory with the original source code and other files built in place.
+
+ Please note that custom sub-commands **SHOULD NOT** rely on ``run()`` being
+ executed (or not) to provide correct return values for ``get_outputs()``,
+ ``get_output_mapping()`` or ``get_source_files()``. The ``get_*`` methods should
+ work independently of ``run()``.
+ """
+
+ editable_mode: bool = False
+ """Boolean flag that will be set to ``True`` when setuptools is used for an
+ editable installation (see :pep:`660`).
+ Implementations **SHOULD** explicitly set the default value of this attribute to
+ ``False``.
+ When subcommands run, they can use this flag to perform optimizations or change
+ their behaviour accordingly.

+ build_lib: str
+ """String representing the directory where the build artifacts should be stored,
+ e.g. ``build/lib``.
+ For example, if a distribution wants to provide a Python module named ``pkg.mod``,
+ then a corresponding file should be written to ``{build_lib}/package/module.py``.
+ A way of thinking about this is that the files saved under ``build_lib``
+ would be eventually copied to one of the directories in :obj:`site.PREFIXES`
+ upon installation.
+
+ A command that produces platform-independent files (e.g. compiling text templates
+ into Python functions), **CAN** initialize ``build_lib`` by copying its value from
+ the ``build_py`` command. On the other hand, a command that produces
+ platform-specific files **CAN** initialize ``build_lib`` by copying its value from
+ the ``build_ext`` command. In general this is done inside the ``finalize_options``
+ method with the help of the ``set_undefined_options`` command::
