This is great! I really, really hope it takes off! C is in dire need of a package manager that can handle dependencies well. OS package managers do not allow multiple versions, and it is extremely difficult to get reproducible builds, because every project has available whatever is installed globally on your machine.
I have used sbt, nimble, leiningen, maven, npm, cargo, conda, and while each of those has its own issues, I would take any of them when working with C.
I have tried biicode, that was showing some promise, but it seems it is not gaining traction...
