Appmon not working with rebar

I recently setup my development environment using rebar. However, my two favorite debugging modules weren’t getting bundled into my development release appmon:start() and tv:start() were returning undefined. If you want to enable tv and appmon you will need to bundle them into your rebar release. You can do this by editing your reltool.config in rebar. Like so:

{rel, "appname", "1",
  {tv, load}
  {appmon, load}

Build your release and appmon and tv should be available :)
