An example of creating a package

var call_counter = require('./call_counter');
var simple_math = require('./simple_math');

function divide(x,y){
	call_counter();
	return x / y;
}

function multiply(x,y){
	call_counter();
	return x * y;
}

function fibo(count){
	call_counter();
	return private_fibo(count);
}

function private_fibo(count, counter, first, second) {
if (count == 0) return 0;
if (counter == undefined) {
counter = 1
first = 1;
second = 2;
}
result = first + second;
if (counter == count) return result;
private_fibo(count, ++counter, second, result)
return result;
}

module.exports = {
					division : divide,
