This project used to be a part of [web-monitoring-processing](https://github.com/edgi-govdata-archiving/web-monitoring-processing/), which contains a wide variety of libraries, scripts, and other tools for working with data across all the various parts of EDGI’s Web Monitoring project. The goal of this initial release is to create a new, more focused package containing the diff-releated tools so they can be more easily used by others.
This release is more-or-less the same code that was a part of `web-monitoring-processing`, although the public API has been rearranged very slightly to make sense in this new, stand-alone context.
