Initialization and Startup

What happens on initialization of Brewtarget? When something goes wrong, where to look for? These are questions that might lead you to look at this page on the initialization of the application. Maybe you're just curious. Either way, welcome.

Since this describes pieces of code, it is bound to be outdated at some point. Most probably, the high level overview should be fine.
