+    vCARD
+
+        The vCard output is intended to be in a format that enables
+        waypoints to be viewed with an Apple iPod. This is achieved by
+        mapping waypoint fields into vCard fields that can be displayed
+        as 'Contacts' on the iPod. With the iPod mounted as a hard disk
+        (see your iPod manual for instructions), the resulting VCF
+        file should be moved into the iPod 'Contacts' folder. As an
+        alternative, Mac OS X users may prefer to drag the VCF file into
+        their address book and synchronize with the iPod using iSync. By
+	default hints are unencrypted; use the 'encrypt' option to
+        encrypt the hints.
