title: Is it possible to configure logback logger levels on the command line?
body: <p>Log4J allows you to pass the level you'd like particular loggers in your application to log at from the command line, e.g. "-Dlog4j.logger.com.whatever.MyClass=DEBUG".  I can't find any similar facility in Logback.  According to the FAQ, all it seems to allow you to do is set the level for the root logger by using variable substitution.  Is there something I'm missing or does Logback just not support this?  Thanks.</p>
