I've seen Log4cxx a bit and am confused as to what it's purpose actually is.
Originally when I saw Logger I assumed it was a key to access a system (that without it you couldn't get the information that you needed). Though looking more at it, it seems to be more of a tracking system? But a tracking system for what and what would one use as a "logger" then?
I'm sorry if this question is vague, but hence my not understanding it :p
I have found this: http://www.yolinux.com/TUTORIALS/Log4cxx.html but no one seems to give a why you use it and how it's beneficial. Can anyone give me an example? I think that's the biggest piece I'm missing.
