title: ghprb - adding content to build status messages?
body: <p>We're using <a href="https://github.com/janinko/ghprb" rel="nofollow">ghprb</a> in all of our repos and it's great. I'd like to be able to add content to the post-build information displayed in git though. We use clover, findbugs, etc and most people are missing the output of these.</p>
  
  <p>ghprb does great returning messages like</p>
  
  <blockquote>
    <p>All is well — Build finished. n tests run, m skipped, k failed.</p>
  </blockquote>
  
  <p>there's even a link back to the jenkins job there.</p>
  
  <p>In the README it intimates that customizations are possible.</p>
  
  <blockquote>
    <p>You can extend the standard build comment message on github creating a comment file from shell console or any other jenkins plugin. Contents of that file will be added to the comment on GitHub. This is useful for posting some build dependent urls for users without access to the jenkins UI console.</p>
  </blockquote>
  
  <p>But no more detail after that. Has anyone managed to add / modify the default content? </p>
