AiwSourceCode question

Good morning

I hope this is the correct Forum section.
I found the source Code from aiw on the Internet.
I want to understand this Code to rewrite it, because i want to learn more about Servercommunication and bigger Projects in C.
Now iam looking for someone who can explain me what everything in this Folder does, because its really hard to work for me threw the whole Code.
I hope someone can help me.

With friendly regards, Chris
