GNU Bison

GNU Bison is like a helper for computer programmers who are making computer programs that understand human languages. Let's say you want to make your computer program understand what people are saying in English or French. You would use GNU Bison to help you make rules for the computer program to follow so it can understand what people are saying.

Like when we talk to our parents, we have to follow rules like say "please" and "thank you" or clean up our toys. In the same way, you have to give rules to your computer program for understanding languages. Bison helps you write these rules faster and more accurately than if you did it all by hand.

So when someone talks to your program in English or French, your program will use these rules you made with Bison to understand what they're saying and give a good response. It's like having a really smart language translator working for you!
