Hi logback dev, I have a jar with logback ,but our user is using various third part log jar ,like log4j and so on , if they dont config the my logpath ,or they dont even use logback , then my log will be in their configpath file ,i mean my log will output to the user's log path ,or my configpath will be lost ,how do i solve this problem?
