The following is a simplified version of the script used on AppVeyor:
```
set PYTHON=C:\Python38\bin
cd /D C:\Pillow\winbuild
C:\Python37\bin\python.exe build_prepare.py -v --depends=C:\pillow-depends
build\build_dep_all.cmd
build\build_pillow.cmd install
cd ..
path C:\Pillow\winbuild\build\bin;%PATH%
%PYTHON%\python.exe selftest.py
%PYTHON%\python.exe -m pytest -vx --cov PIL --cov Tests --cov-report term --cov-report xml Tests
build\build_pillow.cmd bdist_wheel
