Is there a class or sequence diagram for BitcoinCore? I'm looking at the code located at https://github.com/bitcoin/bitcoin/tree/master/src

Does anyone have a basic diagram of what calls what, just a sequence chart of how all the classes piece together and what's a good entry point.  There was a thread with some overview but there has been a lot of change since it seems.  Just wondering if anyone has gone through this process.
You can use source code browsing tools like Source Insight(proprietary) or doxygen(Free software) to create dependency diagram of functions and files.

The doxygen documentation for Bitcoin source can also be found at https://dev.visucore.com/bitcoin/doxygen/
