## Package org.apache.commons.logging.impl Description

Spring's variant of the Commons Logging API: with special support for Log4J 2, SLF4J and `java.util.logging`.

This `impl` package is only present for binary compatibility with existing Commons Logging usage, e.g. in Commons Configuration. `NoOpLog` can be used as a `Log` fallback instance, and `SimpleLog` is not meant to work (issuing a warning when used).
