Question

How do I export multiple 'sub-modules' from one node.js module?

Here's what I mean by exporting 'sub-modules':

var fibers = require('fibers');         // this works, it's the 'main' module
var future = require('fibers/future');  // this also works, it's a 'sub'-module

How would I do this 'abc/xyz' export? I've gone through the fibers source code a little bit, and it doesn't seem like this is something that node/npm will do for me.

javascript
node.js
module
npm

It represents an actual filesystem path. So, in the root directory of your abc module, call a file xyz.js or xyz.json, or create an xyz/ directory with an index.js.
