+<p>
+Useful for storing a vector of values using only a few number of bits for each
+value. Apart from the standard operations of a vector-like container, it can
+also perform an 'or' set operation. 
+</p>
+
+<p>For example:</p>
+
+<div class="doc_code">
+<pre>
+enum State {
+    None = 0x0,
+    FirstCondition = 0x1,
+    SecondCondition = 0x2,
+    Both = 0x3
+};
+
+State get() {
+    PackedVector&lt;State, 2&gt; Vec1;
+    Vec1.push_back(FirstCondition);
+
+    PackedVector&lt;State, 2&gt; Vec2;
+    Vec2.push_back(SecondCondition);
+
+    Vec1 |= Vec2;
+    return Vec1[0]; // returns 'Both'.
+}
+</pre>
