+ Important Note!!
+ ================
+
+The purpose of this folder is to contain files that are auto-generated by the Introjucer,
+and ALL files in this folder will be mercilessly DELETED and completely re-written whenever
+the Introjucer saves your project.
+
+Therefore, it's a bad idea to make any manual changes to the files in here, or to
+put any of your own files in here if you don't want to lose them. (Of course you may choose
+to add the folder's contents to your version-control system so that you can re-merge your own
+modifications after the Introjucer has saved its changes).
