If you'd like to run JSLint locally, you can do so with the aid of
Mozilla's Rhino

http://jslint.com/rhino/

The documentation is sparse, but here's how to install JSLint on your
local machine (assuming you already have Java installed):

1. Download jslint.js from http://jslint.com/rhino/jslint.js
    (make sure you use that particular jslint.js, as its specially
modified to work with Rhino).

2. Get the Rhino zip file from http://www.mozilla.org/rhino/download.html

3. Open the zip and grab js.jar

Then you should then be able to invoke JSLint on any JavaScript file,
from the command window (Mac/PC/Linux) like this:

java -jar js.jar jslint.js someFile.js
