I am currently planning to study the C++ source code of the Snort project on GitHub, but I am not sure where to start. Specifically, I am unsure about which file is the entry point, or which file the developers began writing the code from.

Could someone please guide me on how to identify the main entry point of the Snort project?

Any insights into the structure or files that could be helpful for understanding the flow of the program would be greatly appreciated.
