+description = """optking (also known as pyoptking) is a rewrite of the 
+c++ optking module in psi4. This rewrite was undertaken to enable future 
+development and for use with recent interoperability efforts (e.g. 
+MolSSI QCArchive and QCDB). optking is focused on optimization of 
+molecular geometries: finding minima, transition states, and reaction 
+paths. Current work is focused especially on expanding the reaction path methods."""
