title: Why does wget output to stderr rather than stdout?
body: <p>After 30mins of futile attempt to capture the output of <code>wget</code>, I figured out that the program writes to <code>stderr</code> rather than the <code>stdout</code>. Searching in web and stack-overflow reveals this to be a well-known fact.</p>
  
  <p>Any idea why is this so?</p>
