[logback-user] Does logback support multiple configuration files (logback.xml) for a single application?

Hi, Here is what I am trying to do: 1. create an infra jar that other application depends on. In this jar file, there will be a logback.xml file for some default logging. 2. if other application defines its own logback.xml, I want the application uses both the logback.xml files. Does logback support that? Thanks a lot for your help! -David
