title: Ansible condition for comment
body: <p>Is it possible to add a condition before to run a playbook which check if there is a title (my case it is a comment) on the playbook ?</p>
  <p>For example :</p>
  <pre><code>#Changed by Peter
  #This playbook is for apache
  #version 2.1.1
  ---
    task:
      xxxxxx
  </code></pre>
  <p>And checked if the #Changed by Peter and the rest are on the playbook before to run it
  I checked different kind of conditions but nothing works...</p>
