title: Add new service to existing supervisord process
body: <p>Say I already have a supervisord process running on my machine. How can I add a new service/process for supervisord to monitor? For example, assume I have this simple .conf file:</p>
  
  <h3>run-suman-daemon.conf</h3>
  
  <pre><code>[program:suman-daemon]
  command=/Users/alexamil/WebstormProjects/suman/cli/suman-daemon.sh
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>supervisord add run-suman-daemon.conf
  </code></pre>
  
  <p>but I get this error:</p>
  
  <pre><code>Error: positional arguments are not supported: ['add', 'sup.conf']
  For help, use /usr/local/bin/supervisord -h
  </code></pre>
  
  <p>The <code>supervisord</code> daemon is running and I can connect to it with <code>supervisorctl</code></p>
