Installing

Clone the repository

git clone --recurse-submodules https://github.com/fabienlacasa/PySSC.git

Note that the –recurse-submodules argument also installs the AngPow submodule

Then either put the path to PySSC.py in your $PYTHONPATH, or install the package with pip

pip install -e .

Note that the pip method does not (yet) work for routines using AngPow.
