I am using logback with slf4j in my Maven Java project. Currently logback config file (logback.xml) is in `src -> main -> resources` folder. And it is working fine.

My issue is, I need to give my client the ability to configure logging as he prefers. For that logback.xml should be outside the jar when I build it. But as xml is inside src folder it is inside the jar and no one can change it after build.

How to achieve this?
