‚ÄčAt the end of the day, it's a multi-conformational RESP fit using a
HF/6-31G*-derived MEP, which fits the prescription for the Merz-Kollman
charge derivation scheme. It also shows users how resp works, which they
can then take and extend to include multiple orientations, for instance.

There is value to providing a workflow that can be scripted and run on a
computer in which all components of the workflow can be downloaded and
installed locally. The perl RED scripts are candidates, but you regularly
discourage their use in favor of a solution that is only available through
a web interface.
