+// | getID3() returns a lot of information. Much of this information is   |
+// | not needed for the end-application. It is also possible that some    |
+// | users want to extract specific info. Modifying getID3() files is a   |
+// | bad idea, as modifications needs to be done to future versions of    |
+// | getID3().                                                            |

+// | Modify this wrapper class instead. This example extracts certain     |
+// | fields only and adds a new root value - encoder_options if possible. |
+// | It also checks for mp3 files with wave headers.                      |
