+This command copies from one source device or file C<src>

+would use this to copy to or from a device or partition, for
+example to duplicate a filesystem.

+If the destination is a device, it must be as large or larger
+than the source file or device, otherwise the copy will fail.
+This command cannot do partial copies.");
