SIMPLE LOGGING FACADE FOR JAVA (SLF4J)

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
deployment time.

Before you start using SLF4J, we highly recommend that you read the two-page
SLF4J user manual.

Note that SLF4J-enabling your library implies the addition of only a single
mandatory dependency, namely slf4j-api.jar. If no binding is found on the class
path, then SLF4J will default to a no-operation implementation.

In case you wish to migrate your Java source files to SLF4J, consider our
migrator tool which can migrate your project to use the SLF4J API in just a few
minutes.

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 legacy APIs.
