node.js function to create full directory path (like mkdir -p)

gistfile1.js

exports.createFullPath = function createFullPath(fullPath, callback) {
	var parts = path.dirname(path.normalize(fullPath)).split("/"),
		working = '/',

			callback(null);
			return ;

		var working = paths.shift();
		
		try {
			path.exists(working, function(exists) {
				if(!exists) {
					try {
						fs.mkdir(working, 0755, function() {
							recursePathList(paths);
