+    There is a license exception for this particular file (Settings.java) -
+    you may modify it as you wish without releasing source code,
+    as long as the libraries in the binary package you're distributing
+    (typically libapplication.so and other closed-source libraries in your .apk file)
+    can be linked and executed without error against the SDL compiled
+    from the original source code. This implies that you may not modify Java-to-C
+    interface, otherwise you have to publish the source code with your changes.
+
+    This exception is here to permit you to replace a rather awkward SDL startup config dialog
+    with your own user-friendly version, possibly with lesser options and some help on them.
+    Also you may put your own logo in the startup screen instead of the "Powered by SDL" logo.
+
+    You may modify other Java files if needed to implement your custom startup config dialog
+    without publishing the source code, to a reasonable extent of course - if your modification
+    will make SDL work better, faster or more stable beyond the startup config dialog -
+    you still have to publish the source code with such change (and I don't care about
+    changes which will make SDL work worse, slower or less stable, you may keep them).
