DUtil Project Started

I started a new open source project dutil on google code. dutil (currently 21 units) is aimed to be a cohesive and comprehensive library for general purpose usage. We write code based on Design by Contract principle. We use many pre- and post-conditions to assure the code works properly as expected. We also raise and capture exceptions in code, which makes the logic of code looks perfectly clear. Please feel free to use it and to share it.
