[erlang-questions] OTP R16B01 has been released

With each new release that this happens, I remember that I have not yet submitted a patch to the application module to include the lines I put in all my apps:

https://github.com/archaelus/erlang-factory-2012-example/blob/master/src/ef_app.erl#L25 and https://github.com/archaelus/erlang-factory-2012-example/blob/master/src/ef_app.erl#L70-L79

These lines together allow you to specify your direct dependencies in your .app file, and use 'AppMod:start().' or 'erl -s AppMod' to do a recursive start of your app and all its transitive dependencies.

Interestingly, with correct OTP .app files, 'application' has enough information to start my app and all its dependencies. Currently 'application' is a bit of a jerk - it tells me the exact app that it could have started for me, that is a missing start dependency for the app I am trying to start.

These lines may make development a little easier for you right now, and either I, or someone soon to be on my famed Holiday Card List, will hopefully fix this wart before R16B02.

Anyone have suggestions for a function name for this feature? application:recursive_start/2? application:start_recursively/2? application:run/2?
