+wheel
+=====
+
+This library is the reference implementation of the Python wheel packaging
+standard, as defined in `PEP 427`_.
+
+It has two different roles:
+
+#. A setuptools_ extension for building wheels that provides the
+ ``bdist_wheel`` setuptools command
+#. A command line tool for working with wheel files
+
+It should be noted that wheel is **not** intended to be used as a library, and
+as such there is no stable, public API.
+
+.. _PEP 427: https://www.python.org/dev/peps/pep-0427/
+.. _setuptools: https://pypi.org/project/setuptools/
+
+Documentation
+-------------
+
+The documentation_ can be found on Read The Docs.
+
+.. _documentation: https://wheel.readthedocs.io/
+
+Code of Conduct
+---------------
+
+Everyone interacting in the wheel project's codebases, issue trackers, chat
+rooms, and mailing lists is expected to follow the `PSF Code of Conduct`_.

+(So if file starts with this field it contains only one version).
+
+After filed Mach-O there are section fields.
+Each of them starts with two fields:
+cmd - magic number for this command
+cmdsize - total size occupied by this section information.
+
+In this case only sections LC_VERSION_MIN_MACOSX (for macosx 10.13 and earlier)
+and LC_BUILD_VERSION (for macosx 10.14 and newer) are interesting,
+because them contains information about minimal system version.
+
+Important remarks:
+- For fat files this implementation looks for maximum number version.
+ It not check if it is 32 or 64 and do not compare it with currently built package.
+ So it is possible to false report higher version that needed.
+- All structures signatures are taken form macosx header files.
+- I think that binary format will be more stable than `otool` output.
+ and if apple introduce some changes both implementation will need to be updated.
+- The system compile will set the deployment target no lower than
+ 11.0 for arm64 builds. For "Universal 2" builds use the x86_64 deployment
+ target when the arm64 target is 11.0.

+"""For neatly implementing static typing in packaging.
+
+`mypy` - the static type analysis tool we use - uses the `typing` module, which
+provides core functionality fundamental to mypy's functioning.
+
+Generally, `typing` would be imported at runtime and used in that fashion -
+it acts as a no-op at runtime and does not have any run-time overhead by
+design.
+
+As it turns out, `typing` is not vendorable - it uses separate sources for
+Python 2/Python 3. Thus, this codebase can not expect it to be present.
+To work around this, mypy allows the typing import to be behind a False-y
+optional to prevent it from running at runtime and type-comments can be used
+to remove the need for the types to be accessible directly during runtime.
+
+This module provides the False-y guard in a nicely named fashion so that a
+curious maintainer can reach here to read this.
+
+In packaging, all static-typing related imports should be guarded as follows:
+
+ from packaging._typing import TYPE_CHECKING
+
+ if TYPE_CHECKING:
+ from typing import ...
+
+Ref: https://github.com/python/mypy/issues/3216

+# but True while type checking.
+if False: # pragma: no cover
+ from typing import TYPE_CHECKING
+else:

+
+# typing's cast syntax requires calling typing.cast at runtime, but we don't
+# want to import typing at runtime. Here, we inform the type checkers that
+# we're importing `typing.cast` as `cast` and re-implement typing.cast's
+# runtime behavior in a block that is ignored by type checkers.
