title: Jenkins Custom Email Generation
body: <p>I have been using <em>Jenkins</em> as my automation server for the last couple of weeks. So far so good.</p>
  
  <p>Now I need to generate notification upon build completion. I am using the <em>Email-ext plugin</em> for this. </p>
  
  <p>However, I need to add some custom content into the email content. So far I was using the default ${DEFAULT_CONTENT}. Is there an easy way to append some custom content from a file.</p>
  
  <p>Looks like I need to extend the groovy-text template. However I am willing to know whether is there an easy way to append text from a file easily.</p>
