License text not included in source distribution

[akaihola]

The LICENSE file in this tableau/server-client-python repository contains the MIT license text. When building a source .tar.gz distribution, the file is omitted:

$ git clone -q https://github.com/tableau/server-client-python.git
$ cd server-client-python
$ python setup.py sdist
running sdist
[...]
Creating tar archive
removing 'tableauserverclient-0.4.1' (and everything under it)

$ tar tvf dist/*.tar.gz | egrep 'LICENSE|setup\.py|MANIFEST\.in'
-rw-rw-r-- myself/myself   754 2017-09-19 13:25 tableauserverclient-0.4.1/setup.py
-rw-rw-r-- myself/myself    62 2017-09-19 13:25 tableauserverclient-0.4.1/MANIFEST.in

As a result, also the tarball downloadable from PyPI doesn't contain any license text:

The only mention of the license in the source distribution is license='MIT' in setup.py, which is not sufficient. I believe this omission prevents e.g. our company from installing the library on our customers' servers.

For an example of how to ensure inclusion of the license file, please see the Python Packaging User Guide and the sample project it provides containing the MANIFEST.in and setup.py files.

Also, it seems that versioneer.py isn't distributed under the MIT license, but CC0-1.0. Is it actually necessary to include versioneer.py in MANIFEST.in and thus in the source distribution, since it has already done its job at that point? The _tableauserverclient/_version.py it generates gets included (and that file by the way is also under CC0-1.0). That license is not mentioned in setup.py.
