And this is something I don't understand. If I have a dependency on a
library (say its called libutils) and I put a dependency in the
{applications,[]} tuple of my project's app file - what happens!? The
application cannot launch because the OTP application module does not
understand that this is a library dependency (and not an application)
and therefore tries to start the application, which fails because it's
not an application. If you used a custom tuple in the project's .app
file (say {libs, [...]} for example) then this would work fine and the
OTP application module would just ignore it.
