corresponding java.util.logging.Logger instance. LogKit from Apache's Avalon project. Each named Log instance is connected to a corresponding LogKit Logger. NoOpLog implementation that simply swallows all log output, for all named Log isntances. SimpleLog implementation that writes all log output, for all named Log instances, to System.err. Quick Start Guide For those impatient to just get on with it, the following example illustrates the typical declaration and use of a logger that is named (by convention)...

 of models you may specify:

 all of the models that you specify are collected to produce a lineage and then the super model is place at
 the top of that lineage to provide default values.

 The super model is where we place all the values which we believe to be standard, values that can be shared and
 utilized across all your Maven projects.

            Other values define only the prefix of classes/resources being exposed. Their binary name must be equal to the prefix or starting with the prefix (followed by "." or "$").
