Passing args to a JS command line utility (Node or Narwhal)

I want to use NodeJS or Narwhal to create a JS utility which takes an argument, like so:

$ node myscript.js http://someurl.com/for/somefile.js

or

$ js myscript.js http://someurl.com/for/somefile.js

but I'm wondering how I can get that argument within my script, or if that is even possible atm?

Thanks.

This things now are very easy to do, using stdio module for NodeJS.

You can use optimist, a module for node.js that makes processing args a bit easier.

process.arg[2] should be the reference. Check for process.argv.length to see if it's 3.

On Node.JS, that information is available in process.argv.
