+        <section name="Differences to Ant 1.x">
+
+            <p>Some of the differences between Ant 1.x and Myrmidon:</p>
+            <ul>
+                <li>
+                Groups of tasks can be assembled into self-describing
+                    <i>antlib</i> task libraries.  This makes it very easy to
+                distribute and install tasks and data-types.
+                </li>
+                <li> A project can import other projects, and reference their targets. </li>
+                <li>Properties and data type references now share the same namespace.</li>
+                <li>
+                Changes to task and data-type API:
+                    <ul>
+                        <li>An interface based API, through which a task interacts with the
+                        task engine, and the services it provides.</li>
+                        <li>A well-defined object lifecycle.</li>
+                        <li>Polymorphic types are supported when objects are configured.</li>
+                        <li>Reference handling is handled automatically when objects are configured.</li>
+                        <li>Aspects can be used to decorate tasks, to add facilities like logging,
+                        error handling, or user preferences.</li>
+                    </ul>
+                </li>
+                <li>A set of well-defined services and APIs have been introduced, to allow
+                tasks to do their work without depending on other tasks:
+                    <ul>
+                        <li>Execute external commands.</li>
+                        <li>Execute other tasks.</li>
+                        <li>Manage ClassLoaders and Class-paths.</li>
+                        <li>Virtual file system (in progress).</li>
+                        <li>Execute Java applications (in progress).</li>
+                        <li>...</li>
+                    </ul>
+                </li>
+            </ul>
+            <p>There are plenty more features planned.  You can read about them
+                <a href="todo.html">here</a>.
