Detailed Description

Provides a Python class for parsing a PSF file and setting up a system

structure for it within the OpenMM framework.



This file is part of the OpenMM molecular simulation toolkit originating from

Simbios, the NIH National Center for Physics-Based Simulation of Biological

Structures at Stanford, funded under the NIH Roadmap for Medical Research,

grant U54 GM072970. See https://simtk.org.  This code was originally part of

the ParmEd program and was ported for use with OpenMM.
