This library lets us use multiple logging implementations through an agnostic interface, and the implementations to choose from include slf4j, log4j, and logback. Let's quickly skim over how we can add logging to any Clojure program using the tools.logging library and logback, which is arguably the most recent and configurable implementation to use with this library.
