> "...how I learn an unfamiliar codebase"

There should be more writing and discussion in this area for several reasons. Simplest reason because we're curious about how others do this. But also because it's an interesting topic, IMHO, because layers of abstraction--code designed to run other code--can be difficult to talk about, because the referents get messy. How do you rhetorically step through layers of abstraction?
