/**
* Jakarta Commons Logging listener.
* Note: do not use the SimpleLog as your logger implementation as it
* causes an infinite loop since it writes to System.err, which Ant traps
* and reroutes to the logger/listener layer.
*
* The following names are used for the log:
* org.apache.tools.ant.Project.PROJECT_NAME - for project events
* org.apache.tools.ant.Target.TARGET_NAME - for target events
* TASK_CLASS_NAME.TARGET_NAME - for events in individual targets.
*
* In all target and project names we replace "." and " " with "-".
*
* TODO: we should use the advanced context logging features (and expose them
* in c-l first :-)
* TODO: this is _very_ inefficient. Switching the out and tracking the logs
* can be optimized a lot - but may require few more changes to the core.
*
* @since Ant 1.5
