ATS Correspondence
==================

This library began as a set of classes in `Apache Traffic Server<https://trafficserver.apache.org>`__.
It has continued to be driven primarily by usefulness in writing ATS core and plugin code. For that
reason it should be incorporated back in to ATS as a replacement for existing classes.
