title: How to find which library slf4j has bound itself to?
body: <p>I am using slf4j for logging in my application.
  I get the purpose of slf4j. I would like to know how to find out which logging-library slf4j is currently binding to. I have log4j in my referenced libraries. I am assuming that slf4j has bound itself to log4j.</p>
  
  <p>What I would like to know is, is there any way to explicitly confirm this binding?</p>
