What is cowboy coffee?

Can you tell me more about cowboy coffee? I've heard it's a unique brewing method with a rich history. How exactly is it made? Does it differ from other coffee-making methods in any significant way? I'm particularly interested in the flavor profile and how it compares to more traditional brewing techniques. Additionally, are there any specific tools or equipment required to make cowboy coffee, or can it be prepared with minimal resources? I'm eager to learn more about this fascinating aspect of coffee culture.
