up to 7 arguments??? what mean ?? thank you !

Example:

$ ./create-cluster call SET mykey hello
                         ↑    ↑     ↑
                   command  arg   arg

SET is the command name. mykey and hello are two arguments.

Some commands accept more than 7 arguments, but with create-cluster call, maximum 7 can be used.
