Parsing booleans in Robot Framework
<p>The <a href="http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#boolean-arguments" rel="nofollow">Robot Framework User Guide, section 6.6 Boolean arguments</a>, says:</p>

<blockquote>
  <p>Many keywords in Robot Framework standard libraries accept arguments
  that are handled as Boolean values true or false. If such an argument
  is given as a string, it is considered false if it is either empty or
  case-insensitively equal to false or no. Other strings are considered
  true regardless their value, and other argument types are tested using
  same rules as in Python.</p>
</blockquote>

<p>How do I replicate this behavior in my own user keywords?</p>

<p>The build-in keyword <code>Convert To Boolean</code> is stricter:</p>

<blockquote>
  <p>Converts the given item to Boolean true or false.</p>
  
  <p>Handles strings True and False (case-insensitive) as expected,
  otherwise returns item's truth value using Python's bool() method.</p>
