title: How to use logback in a PlayFramework project
body: <p>Because of dependencies on a project I am working on developing a web application using the Play!Framework, I have to configure logback to prevent it from flooding my output with DEBUG messages.
  But as log4j is the default log library used by the Play!Framework, I don't really know how to make it consider a logback.xml configuration file.</p>
  
  <p>The best would be to make the Play!Framework completely use logback/Slf4j instead of log4j. How could I do this ?</p>
