+	<para>
+	Ebuild execution is divided into a series of phases. In order
+	to implement a phase, an ebuild defines a function to serve as
+	an entry point for execution of that phase.
+	This design is similar to the template method pattern that
+	is commonly used in object oriented programming languages. An ebuild
+	can inherit or override a template method from an eclass.
