+<!--
+    Debug visualizers for a few common ScummVM types for Visual Studio 2012 and up.
+
+    To use, copy this file into Documents\Visual Studio 20xx\Visualizers.
+
+    Known issues:
+
+    * Lists appear to be infinite (the same elements repeat over and over again).
+      Unfortunately, Lists don't store length information, and it's not possible to
+      detect whether a Node is the last one by the Node itself.
+
+    * In HashMaps, missing and dummy nodes are shown along with the useful ones.
