-P, --parameterized-uri[=true|false] Enable parameterized URI support.
You can specify set of parts:
http://{sv1,sv2,sv3}/foo.iso
Also you can specify numeric sequences with step
counter:
http://host/image[000-100:2].img
A step counter can be omitted.
If all URIs do not point to the same file, such
as the second example above, -Z option is
required.
