This is the Python built-in tkinter module, except supplied separately.
It is useful when using a build of Python that does not have tkinter included, such as in a virtual environment on an Ubuntu installation without python3-tk.

To build the wheel, just type:
python setup.py bdist_wheel
On Windows and macOS, the dependencies are copied automatically.
On Linux, you need to use auditwheel to do this, but see the included
build_manylinux.sh
script.
The tkinter
directory is lifted from the Python source, so its license is
that of the Python source (Python Software Foundation license).
