+ * Class for holding copyright information.
+ *
+ * The Exif standard specifies a certain format for copyright
+ * information where the one {@link PelTag::COPYRIGHT copyright
+ * tag} holds both the photographer and editor copyrights, separated
+ * by a NULL character.
+ *
+ * This class is used to manipulate that tag so that the format is
+ * kept to the standard. A common use would be to add a new copyright
+ * tag to an image, since most cameras do not add this tag themselves.
+ * This would be done like this:
+ *
+ * <code>
+ * $entry = new PelEntryCopyright('Copyright, Martin Geisler, 2004');
+ * $ifd0->addEntry($entry);
+ * </code>
+ *
+ * Here we only set the photographer copyright, use the optional
+ * second argument to specify the editor copyright. If there is only
+ * an editor copyright, then let the first argument be the empty
+ * string.
