title: What is the shortest way to get log4j initialized in your main method?
body: <p>I want everything to log to the console and don't want to have to deal with creating log4j.xml files, etc. I am prototyping some libraries and want to see their full log output.</p>
  
  <p>I would like to keep it as pure as possible and not have to introduce unnecessary dependencies like Spring, etc.</p>
