title: Setting log level of message at runtime in slf4j

We're using this fact and <a href="http://www.mail-archive.com/log4j-user@logging.apache.org/msg05005.html" rel="noreferrer">this tip</a> to redirect stderr to a logger at a specific log level.</p>
  
  <p>slf4j doesn't have a generic <code>log()</code> method that I can find. Does that mean there's no way to implement the above?</p>
