if there is one.
+Windows
+-------
+
+- bpo-30450: The build process on Windows no longer depends on Subversion,
+ instead pulling external code from GitHub via a Python script. If Python 3.6
+ is not found on the system (via ``py -3.6``), NuGet is used to download a
+ copy of 32-bit Python.

+If Python 3.6 or later is not available via the "py.exe" launcher, the
+path or command to use for Python can be provided in the PYTHON_FOR_BUILD

It is also possible to download sources from each project's homepage,
though you may have to change folder names or pass the names to MSBuild
