title: Change variable in Layout from view script
body: <p>in my layout i have things like meta tags etc. that may change in e.g. in different static sites.</p>
  
  <p>Example:
  if i go to
  /static/about
  i would like to have a different meta-description as in
  /static/contact</p>
  
  <p>My Problem is that i would like to change these variables/values inside the view script static/content/about or static/content/contact and NOT in the controller.</p>
  
  <p>How can i do that?</p>
