X²Utils is an open-source set of utility classes and functions released under the zlib/libpng license, a copy of which is shown below. It's main function is reusability and convenience; anything which is used often deserves a spot in the library, assuming it is written with portability in mind.

The official website for X²Utils is located at http://x2utils.kamadev.net/. Contributions to the source code are appreciated, and after reviewing will be committed to the Subversion repository.
