const clp = require("clparser");
const parser = new clp.ClParser({
    offset: <number>,           // default: 2
    optionPrefix: <string>,     // "/", "-", or "--", default: "/"
    caseSensitive: <boolean>    // default: false
});

parser.offset               Number, default: 2
parser.optionPrefix         String, "/", "-", or "--", default: "/"
parser.parameterCount       Number of parameters (readonly, no options or switches)
parser.options              Array of objects [{ option<1>: value }, ..., { option<n>: value }] (readonly). 
                            Does not follow the caseSensitive option.
parser.parameters           Array (readonly, no options or switches)
parser.switches             Array of strings [ switch<1>, ..., switch<n> ] (readonly).

parser.option(name)         Get the value of the named option
parser.parameter(index)     Get the command line parameter indicated by index
parser.switch(name)         Returns boolean value that indicates whether the named switch exist
