Thanks Yingyi for your prompt reply and help. w.r.t my question about documentation, I have been aware of the functions documentation and I have been using it. I was mainly looking for a place where keeps track of changes in functions in the sense that if function foo() is replaced with bar() the document captures the change (some sort of similar to deprecated functions in Java docs where it points you to the correct/newer function that needs to be used). However, I guess we do not have such a place and one really needs to keep an eye on the check-in changes list if he uses functions extensively.
Thanks again for your help and info.
