__doc__ = """This is a distutils setup-script for the pywin32 extensions.

The canonical source of truth for supported versions and build environments
is [the GitHub CI](https://github.com/mhammond/pywin32/tree/main/.github/workflows).

To build and install locally for testing etc, you need a build environment
which is capable of building the version of Python you are targeting, then:
  pip install . -v

For a debug (_d) version, you need a local debug build of Python, but must use
the release version executable for the build. eg:
  pip install . -v --config-setting=--build-option=build --config-setting=--build-option=--debug

Cross-compilation from x86 to ARM is well supported (assuming installed vs tools etc) - eg:
  python -m build --wheel --config-setting=--build-option=build_ext --config-setting=--build-option=--plat-name=win-arm64 --config-setting=--build-option=build --config-setting=--build-option=--plat-name=win-arm64 --config-setting=--build-option=bdist_wheel --config-setting=--build-option=--plat-name=win-arm64

Some modules require special SDKs or toolkits to build (eg, mapi/exchange),
which often aren't available in CI. The build process treats them as optional -
instead of a failing, it will report what was skipped, and why. See also
build_env.md, which is getting out of date but might help getting everything
required for an official build - see README.md for that process.
