+
+<p>The <code>(chickadee data array-list)</code> module provides an array/vector
+that dynamically expands to hold all of the data that is added to it.
+It is named after the <code>ArrayList</code> class in Java.
+</p>
+<p>In addition to being used as a dynamic vector, it can also be used as
+a stack via the <code>array-list-push!</code> and <var>array-list-pop!</var>
+procedures.
+</p>
+<dl>
