Hi,

I recently switched to Emacs and still finding my way through it. I code in C++ and was wondering what tools out there extend Emacs to support code browsing (finding a symbol etc), refactoring and code completion. I have heard of:

cedet
etags
cscope

But I'm so confused about what I need. Some places say that cedet provides all of the functionality but other places say that I need to invoke etags for cedet to work properly.

Can someone clear this up for me? Do I need all of these tools?
