For more complex applications, you'll want to build up a ``settings.json` object using multiple environment variables.
if(Meteor.isServer){
Meteor.startup(function()){
// this needs to be run on the server
var environment, settings;
environment = process.env.METEOR_ENV || "...
The METEOR_SETTINGS environment variable can accept JSON objects, and will expose that object in the Meteor.settings object. First, add a settings.json to your app root with some configuration info.

The idea is that a distro maintainer wants to run something like the following command:
meteor publish-release clinical.meteor.rc6.json
Which will then allow users of the distro to run this:
meteor run --release clinical:[email protected]
A release manifest is similar to an NPM package.json file, in that it's primary concern is specify a list of Atmosphere packages, and providing a bit of metadata about that list of packages. The basic format looks like this:

StarryNight contains a small utility that parses an application's .meteor/versions file, and converts it into a Release Manifest.
npm install -g starrynight

If you don't wish to use StarryNight, simply copy the contents of your .meteor/versions file i...
When building a custom release track, it's common to keep packages in the /packages directory as git submodules. The following command allows you to fetch all of the latest commits for the submodules in your /packages directory at the same time.
git submodule foreach git pull origin master
