<h1>Simple Logging Facade for Java (SLF4J)</h1>
<p>The Simple Logging Facade for Java (SLF4J) serves as a simple
facade or abstraction for various logging frameworks
(e.g. java.util.logging, logback, log4j) allowing the end user to
plug in the desired logging framework at <em>deployment</em>
time. </p>
<p>Before you start using SLF4J, we highly recommend that you read
the two-page <a href="manual.html">SLF4J user manual</a>.
</p>
<p>Note that SLF4J-enabling your library implies the addition of
only a single mandatory dependency, namely <em>slf4j-api.jar</em>.
If no binding is found on the class path, then SLF4J will default to
a no-operation implementation.
</p>
<p>In case you wish to migrate your Java source files to SLF4J,
consider our <a href="migrator.html">migrator tool</a> which can
migrate your project to use the SLF4J API in just a few minutes.</p>
<p>In case an externally-maintained component you depend on uses a
logging API other than SLF4J, such as commons logging, log4j or
java.util.logging, have a look at SLF4J's binary-support for <a
href="legacy.html">legacy APIs</a>.
