The Open Forcefield Toolkit provides implementations of the SMIRNOFF format, parameterization engine, and other tools. Documentation available at http://open-forcefield-toolkit.readthedocs.io
Docs builds started failing when a python 3.9-incompatible typing signature was added to a method declaration.
