use my own ILog implementation

[steven higgan]

What I want to do (and I am completely unsure about how to do it) is
that when I call :
static log4net.ILog log = log4net.LogManager.GetLogger("myloggername");

I want the instance of ILog that I get back to be my own implementation of ILog

So how do I go about telling that how to create my instance ? can we
provide a factory or even a func?

thanks.
