Usage

var capture = require('{%= name %}');
var restore = capture(process.stdout);

console.log('Hello, world!!!');
console.log('foo', 'bar');

var output = restore();
console.log(output);
//=> [ [ 'Hello, world!!!\n' ], [ 'foo bar\n' ] ]

Pass true to restore to return a string instead of an array of output.

var capture = require('{%= name %}');
var restore = capture(process.stdout);

console.log('Hello, world!!!');
console.log('foo', 'bar');

var output = restore(true);
console.log(output);
//=> Hello, world!!!
//=> foo bar
//=>

This module has been built to be used in unit tests to easily capture output from process.stdout and process.stderr and test the results.
