cbrun
=====
A very tiny library to invoke callbacks

To install simply run:
```bash
npm install cbrun
```


This lib implements only one function.
You can pass array of errors, what you pass to nested callbacks.
On second argument you must put callback reference, third and further - it is arguments of callback, excluding error.
```javascript
function callbackHandler(errors[], callback, [arg_0, arg_1, ...]);
```
Or you can put one error, but do not forget put callback anyway.
```javascript
function callbackHandler(error, callback, [arg_0, arg_1, ...]);
```

This function exports to module, so you need to require it first:

```javascript
var callbackHandler = require('cbrun');
var fs = require('fs');

//Our function, what invokes callback
function readFiles(callback) {
  fs.readFile('file1', function (err, data1) {
    fs.readFile('file2', function (err1, data2) {
        //You dont need to check error in nested callbacks, only on endpoint
        callbackHandler([err, err1], callback, data1, data2); 
    });
  });
}


//Usage of this function
readFiles(function (err, fileData1, fileData2) {
  if (err) {
    console.log(err);
    process.exit(1);
  }
  console.log(fileData1.toString(), fileData2.toString());
});

```
