+    The difference between <code>runAfter</code> and <code>wrapAfter</code> is subtle but important. <code>runAfter</code>
+    is just a declaration of dependency. It's basically the reverse of <code>runBefore</code> but it's useful in case
+    you are not the author of the task you want to run before (if you were, you would just use the <code>runBefore</code>
+    annotation on it). Since you can't say <code>"a runBefore b"</code> because you don't own task "a",
+    you say <code>"b runAfter a"</code>.
+</p>
+<p>
+    For example, <code>compileTest</code> is declared as a <code>runAfter</code> for the task <code>compile</code>.
+    This means that it doesn't make sense to run <code>compileTest</code> unless <code>compile</code> has run first.
+    However, if a user invokes the task <code>compile</code>, they probably don't want to invoke <code>compileTest</code>,
+    so a dependency is exactly what we need here: invoking <code>compileTest</code> will trigger <code>compile</code>
+    but not the other way around.
+</p>
+<p>
+    However, there are times where you want to define a task that will <strong>always</strong> run after a given task.
+    For example, you could have a <code>signJarFile</code> task that should always be invoked if someone builds a jar
+    file. You don't expect users to invoke that target explicitly, but whenever they invoke the <code>assemble</code>
+    target, you want your <code>signJarFile</code> target to be invoked. When you want such a task to always be invoked
+    even if the user didn't explicitly request it, you should use <code>wrapAfter</code>. You are essentially wrapping
+    an existing task with your own task. Note that there is no <code>wrapBefore</code> annotation since <code>runBefore</code>
+    achieves the same functionality.
