The avalon-logging package is a open logging platform suitable for use by container implementators. It is based largely on the original excalibut logging system but with some important changes. Firstly it leverages the avalon-repository technology to support dynamic loading of implementation strategies, secondly, it simplies the overall approach to target configuration, and thirdly, it applies a formal logging category meta-data model that is consitent with model-driven container solutions. Please note that this package has not been released.
