Why would hidden files be confusing? Or, rephrased, how is this any more 
confusing than other hidden directories, such as .idea or .jib? I 
modelled the behaviour on jib. In fact, I was considering using the same 
directory (.jib), but since the name was so specialized, it felt like 
misusing it. That's why I gave it a more general name. (In fact, I 
believe, if .build had been present when jib was created, it would have 
used that instead of creating the specialized .jib directory).
