-//===--- HowToUseJIT.cpp - An example use of the JIT ----------------------===//
-// 
-//                     The LLVM Compiler Infrastructure
-//
-// This file was developed by Valery A. Khamenya and is distributed under the
-// University of Illinois Open Source License. See LICENSE.TXT for details.
-// 
-//===----------------------------------------------------------------------===//
-//
-//  This small program provides an example of how to quickly build a small
-//  module with two functions and execute it with the JIT. 
-// 
-// Goal: 
-//  The goal of this snippet is to create in the memory
-//  the LLVM module consisting of two functions as follow:
-//
-// int add1(int x) {
-//   return x+1;
-// }
-// 
-// int foo() {
-//   return add1(10);
-// }
-// 
-// then compile the module via JIT, then execute the `foo' 
-// function and return result to a driver, i.e. to a "host program".
-// 
-// Some remarks and questions:
-// 
-// - could we invoke some code using noname functions too?
-//   e.g. evaluate "foo()+foo()" without fears to introduce 
-//   conflict of temporary function name with some real
-//   existing function name?
-//
