title: Parametrizing node name in Elixir Exrm
body: <p>I want to use Exrm with Erlang distributed on a single machine.</p>
  
  <p>I need to create multiple releases that differ only with node name.</p>
  
  <p>I know, I can configure node name in <code>rel/vm.args</code>, but it will be static. Can I somehow generate multiple releases with different node name?</p>
