"Rofretta" is just another time waster project, something fun to hack away on now and then. The idea, if I follow through, is inspired by the ubuitious "todo app" implementation in the web app world. Take a simple premise, reimplement it several times, see what you learn.
Only in this case, instead of doing a todo app, we're going to take on a different domain, guitar chords. We'll tackle a bit of music theory to make it challenging, but we'll try to put a limit on what we plan on implementing (otherwise we'll never have more than one implementation!).
This "common" repo holds files common across all implementations.
