title: Suggest terms to describe language proficiency level in your CV
body: <p>What's the best way to describe your level of skill in particular technologies (languages, platforms, OS, ...) when polishing your CV ?<br>
  Assume we are talking about the <em>short CV</em> of the kind where you don't spell out every project and system you have worked on in the past, but still want the reader to get a general appreciation of how well you master each topic.</p>
  
  <p>Can you suggest a set of labels which is unambiguous but sufficiently general to be understood across the industry?</p>
