The short answer is that in Elixir releases you will be able to do:
bin/my_app eval "MyApp.ReleaseTasks.migrate"
So the code in Distillery still works, you will have to adjust it a bit
though and remove the arg processing bit, as you can call the functions
directly . We will probably have a section about it in the Phoenix guides
once Elixir v1.9 is out.
