"Free software is like free lunch -- it doesn't exist. It takes time and tools to develop software and resources to market and
distribute it. But just as you have the freedom to take lunch, some believe you should have the freedom to copy, modify and distribute
software. This freedom is not available with freeware, shareware or proprietary software -- source code does not accompany these
products. But source code does accompany open-source software." More at Network Computing.
