The limit between Erlang and OTP is really thin. For example, the code server, the bit of running processes in charge of loading new modules in the VM, is a gen_server, an OTP component. Same with the standard library, kernel and whatnot, which are all OTP applications, loaded with the OTP framework. If you dig deep enough, the dependency becomes rather circular.
