tarfile.ReadError: file could not be opened successfully

[RSteendam]

I could not get depccg to work. I first tried installing via pip, then I cloned the repo and tried:

pip install -U cython
python setup.py clean
python setup.py build_ext --inplace
python setup.py install  

However, in both cases, running the depccg_en download then gives:

  warnings.warn('''\

tri_headfirst.tar.gz is only a 2KB file.

Manually downloading and extracting the archive fixed this issue.
