+# This script will search for resources contained in Resources/ folder but not
+# present in xcode build project project.pbxproj. Since we do not use folder
+# references (because of http://vocaro.com/trevor/blog/2012/10/21/xcode-groups-vs-folder-references/),
+# it helps keeping resources synced.
+# Basically, the script will set a red tag to every files not added in the xcode project. User will then
+# have to drag&drop these into xcode project. Red tags are automatically reset by the script on execution
+
