Stakeholder Reach-out: Is this project maintained?

[alexeagle]

The last meaningful commits here, along with the last release, were 2 1/2 years ago by @ekuefler.

If no one maintains this, I think we should either start a discussion to find new maintainers, or archive the repository to clearly set community expectations.

If you use these rules and see this message, it would be great to comment that you depend on them.
