This code snippet helps in reply to a JSHINT pull request here: https://github.com/jshint/jshint/pull/1221. The code is part of a node.js file that programmatically looks through a project's files and outputs the results of jshint for each file.
This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
