title: Override "rspec" command to run tests
body: <p>This seems simple but I can't find a reputable solution via Google or searching SO.</p>
  
  <p>I'm using foreman with a Rails 4 app to load ENV via a .env file. To run my tests properly, I have to execute <code>foreman run rspec [optional files]</code>.</p>
  
  <p>This gets tedious and occasionally I forget the <code>foreman run</code> part.  I'd like to override the <code>rspec</code> command for a single app so that:</p>
  
  <p><code>rspec [files]</code>  => <code>foreman start [files]</code></p>
  
  <p>Looked at binstubs but I don't fully understand them and they don't look exactly like what I want.</p>
  
  <p>I can create a bash script that does this, but now that's specific to my local machine instead of built into the app codebase.</p>
