+  5  MAKE AN APPLICATION LAUNCHABLE BY DROPPING FILES ON ITS ICON
+=================================================================
+- Prepare an Info.plist file for your application derived from file
+ide/Xcode4/plists/editor-Info.plist which allows any file to be dropped
+on the application icon.
+You can edit this file in Xcode and change 
+Document types/Item 0/CFBundleTypeExtensions/Item 0
+from the current "*" to the desired file extension. Use several items to declare 
+several extensions.
+
+- Call fl_open_callback() at the beginning of your main() function that
+sets what function will be called when a file is dropped on the application icon.
+
+- In Xcode, set the "Info.plist File" build setting of your target application
+to the Info.plist file you have prepared.
+
+- Rebuild your application.
