So, this is my first time trying a Cython and I figure the package installation would be the same, but when I try to install using pip, this is what I get:

ERROR: More than one .egg-info directory found in /tmp/pip-pip-egg-info-d3jh1vfk

any ideas?

@AlfredoSequeida I think it means you have some sort of corrupt Cython install from before, or the Cython people messed something up when making the most recent version. Try doing pip install cython==3.0a6, or check out possible solutions here:
pypa/pip#8201

I've never had this issue before personally, and I've never heard of anyone having it, so I'm sorta flying in the dark here.

Added the cythonizer.py script in #21. Once cython is installed, if setup.py doesn't immediately install for you, you can run python3 cythonizer.py build_ext --inplace to install the module.

Closing in favor of #21
