# Appendix H. Project Components This file will give you a quick introduction and a reference of the things that you may see in a build files besides [tasks](apb.html "Appendix B. Core tasks") and [types](apd.html "Appendix D. Core Types"). H.1 Phing Projects Projects are the outermost container for everything in build files. The `<project>` tag also is the root tag in build files. It contains the name, the directory, a short description and a default target. Project may contain task calls and targets (see below). H.1.1 Example ``` <?xml version="1.0" ?> <project name="TestProject" basedir="." default="main" description="This is a test project to show how to use projects ;-)"> <!-- Everything else goes here --> </project> ``` Phing allows declaring tasks outside targets. Note that these tasks are evaluated before any targets are executed.
