Usage: nepho stack create <cloudlet> <blueprint> [-n/--name <stack name>] [-s/--save] [-p/--params <param>]

A custom name for your stack rather than nepho-<cloudlet>-<blueprint>.
When using this option you must specify name for other stack actions such as

-s, --save
[NOT IMPLEMENTED] Save command-line (and/or interactive) parameters to an
overrides file for use in all future invocations of this command.
-p, --params
Override any parameter from the blueprint template. This option can be passed
multiple key=value pairs, and can be called multiple times. If a required
parameter is not passed as a command-line option, nepho will interactively
prompt for it.
