There are numerous versioning utilities out there, but this is something I've built over time because the existing solutions didn't necessarily have the right devex for me.

Most of them generally relied on either a system keeping track of versions, or were invoked via git comments or keywords mentioned in pr titles/descriptions/etc.

I wanted something that worked a bit more seamlessly, configured through code, and without introducing too many dependencies into my pipeline.

There's a corresponding GitHub Action that can be dropped into your jobs as well.

Didn't necessarily need to exist, but it was a fun project to do, and something I've used in my work a bit.
