X²Utils is an open-source set of utility classes and functions released under the <ulink url="http://www.opensource.org/licenses/zlib-license.php">zlib/libpng license</ulink>, 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 documentation for X²Utils is kept both as in-source comments and external docBook format. The in-source comments can be used in combination with <ulink url="http://www.thewsoft.com/">Delphi Component Help Builder</ulink> to generate reference documentation. The docBook sources must be kept in sync manually, but allow for detailed explanation of the various functions.

Note that you should not free the return value of the App() function, the unit's finalization clause takes care of destroying the object when the application closes. This makes it suitable to use the App() function in a way similar to Delphi's Application object.
