                            Does not follow the caseSensitive option.
parser.parameters           Array (readonly, no options or switches)
parser.switches             Array of strings [ switch<1>, ..., switch<n> ] (readonly).

>

const clp = require("@hutechtechnical/excepturi-tempore-nihil-cupiditate");

console.log(parser.option("command"))  -> "copy"
console.log(parser.options)            -> [{ command: "copy", tries:"3" }]
console.log(parser.parameterCount)     -> 2
console.log(parser.parameters)         -> ["source.txt","target.txt"]
console.log(parser.parameter(0))       -> "source.txt"
