+ * When this file is linked to a DLL, it sets up a delay-load hook that
+ * intervenes when the DLL is trying to load 'node.exe' or 'iojs.exe'
+ * dynamically. Instead of trying to locate the .exe file it'll just return
+ * a handle to the process image.
+ *
+ * This allows compiled addons to work when node.exe or iojs.exe is renamed.
