Brief Summary

The motivation for this chapter is to reveal some of the internals of cabal. It shouldn't be a deep dive, but an explanation of where things end up, and some performance considerations that will be useful! It might be a good idea to cover manually busting the cache, and clearing out build artefacts, as well as best practices.
