title: Set Clojure logging level in clojure.tools.logging
body: <p>I would like to set the logging level, but am neither familiar with Java logging nor the deprecated contrib library.</p>
  
  <pre><code>(ns com.etc.etc (:require [clojure.tools.logging :as log]))
  
  com.etc.etc=&gt; (log/info "foo")
  INFO  com.etc.etc.invoke nREPL-worker-1 - foo
  nil
  com.etc.etc=&gt; (log/debug "bar")
  nil
  </code></pre>
  
  <p>I want to set the logging level such that <code>log/debug</code> will be output.</p>
