What's unipackage.json in ~/.meteor/package/*/x.x.x? Are there docs?


#1

I see that some packages (i.e. ~/.meteor/packages/*/<version>/) have empty package.js files, along with isopack.json and unipackage.json files containing info about the package. What are isopack.json and unipackage.json and all those other json files for? What does Meteor do with them? Are there docs for these files somewhere?
