  com.threerings.bureau.util.BureauLogRedirector

public class BureauLogRedirector
extends Object

Captures the output of a bureau and redirects it into a single logger instance using a thread name equal to the bureau id. The Logger instance is the one for this class. The intent is that log4j will be configured to use %t (thread name) to embed the bureau id.
