-// This small program provides an example of how to build quickly a small module
-// with function Fibonacci and execute it with the JIT.
-//
-// The goal of this snippet is to create in the memory the LLVM module
-// consisting of one function as follow:
-//
-//   int fib(int x) {
-//     if(x<=2) return 1;
-//     return fib(x-1)+fib(x-2);
-//   }
-//
-// Once we have this, we compile the module via JIT, then execute the `fib'
-// function and return result to a driver, i.e. to a "host program".
