The Logging package is an ultra-thin bridge between different logging implementations. A library that uses the commons-logging API can be used with any logging implementation at runtime. Commons-logging comes with support for a number of popular logging implementations, and writing adapters for others is a reasonably simple task. See RELEASE-NOTES.txt for details on the current release. Note: The maven2 pom.xml file is affected by the presence or absence of this file. See the comments in that file for details.
