title: Parse out key=value pairs into variables
body: <p>I have a bunch of different kinds of files I need to look at periodically, and what they have in common is that the lines have a bunch of <code>key=value</code> type strings. So something like:</p>
  
  <pre><code>Version=2 Len=17 Hello Var=Howdy Other
  </code></pre>
  
  <p>I would like to be able to reference the names directly from awk... so something like:</p>
  
  <pre><code>cat some_file | ... | awk '{print Var, $5}' # prints Howdy Other
  </code></pre>
  
  <p>How can I go about doing that? </p>
