body: <p>What is a good way to output help text for a bash script to get the columns lines to be lined up properly?</p>
  
  <p>something like:</p>
  
  <pre><code> Usage: mycommand [options]
  
      -h| --help           this is some help text.
                           this is more help text.
      -1|--first-option    this is my first option
      -2|--second-option   this is my second option
  </code></pre>
