requirements.txt is missing from PyPI source tarball

[boegel]

requirements.txt is required by setup.py, but it's missing from the PyPI source tarball, which leads to the following when trying to install arboreto 0.1.6 from source:

    Running command python setup.py egg_info
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/eb-hq4sf4y2/pip-req-build-q_upe322/setup.py", line 17, in <module>
        install_requires=read_requirements('requirements.txt'),
      File "/tmp/eb-hq4sf4y2/pip-req-build-q_upe322/setup.py", line 4, in read_requirements
        with open(fname, 'r', encoding='utf-8') as file:
    FileNotFoundError: [Errno 2] No such file or directory: 'requirements.txt'
