title: How to use a Rails environment variable in Capistrano deploy script?
body: <p>If I have a constant in my Rails environment.rb, for example...</p>
  
  <pre><code>SOME_CONSTANT = 3
  </code></pre>
  
  <p>Is it possible to access this in my capistrano deploy.rb somehow?  It seems simple but I can't figure out how.</p>
