Documentation for the project.

Builds our tar and zip archives and our rpm and deb packages.

Libraries used to build other parts of the project. These are meant to be
internal rather than general purpose. We have no plans to
[semver](https://semver.org/) their APIs or accept feature requests for them.
We publish them to maven central because they are dependencies of our plugin
