+If UBLIO (cache for improving performance) was enabled, see the following to
+know more about it: "ports/sysutils/fusefs-ntfs/files/pkg-message.in".
+
+If FUSE (mount support) was enabled, note that there is no write capability
+and does not allow to browse directories with programs like the GTK+ file
+browser, Midnight Commander, etc. So for mounting it's better to use
+"sysutils/fusefs-ntfs".
