Thank you very much Vinay. You have been extremely helpful.
This was my first design - but then I found that log system was taking
up quite a huge chunk of the memory.
That is why I went to rotating file handler.
Anyways, now I have modified doRollover to append if file is there,
so, for me it is working.
What I was thinking was such an option in the basic logging system
might be of good help.
Again, Vinay, Thank you very much. You were extremely helpful.
