Run multiple iterations of the same command from a stored configuration.

I built this to help with building multiple packages using fpm. I had a set of commands where it was useful to share default and common arguments for each package, and the commands were complex enough that I wanted a configuration file describing them (and generic functions are painful in make). An example of using clack with fpm can be found in examples/fpm.json.


Create a configuration file:

    "default": {
        "command": "cowsay",
        "options": { "-f": "default" }
    "iterations": [
            "arguments": ["moo"]
            "arguments": ["baa"],
            "options": { "-f": "sheep" }

Then run clack on the file:

clack examples/farm.json

And the result:

< moo >
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||
< baa >
            ||    ||
