Been hacking away for quite a while at basically a build tool/framework for Rust, which picks up where Cargo leaves things. So, it's really just a set of libraries for now, which you can use while writing your build scripts in Rust, to help with stuff like putting together a distribution archive, caching intermediate results or handling the automatic installation of CLIs you use in your scripts.

Definitely has been an experience to build this. It feels like a magnitude more work to find generic solutions for this stuff, compared to just throwing it down for a single codebase.
But it has also been rewarding, seeing builds becoming more robust and quicker in the other projects that I'm definitely also still developing and not just using as a testbed for my build tooling. 😅
