Maybe it's just me but having no manifest makes using this tool quite painful. It has taken me 10 mins just to figure out how to structure the require()'s so that it doesn't error out, and that's with only requiring two packages.

For example I created a quick index.js file and required angular and restangular. It immediately errored out because the angular.js repo doesn't use semver on it's master branch. Ok fine, switch to angular/bower-angular, nope, it looks for index.js so my require now has to read: require('angular/bower-angular:angular.js'). Run again, error, same issue with restangular, it's looking for index.js. That require now reads: require('mgonto/restangular:dist/restangular.js'). I had to actually find where the files are that I wanted to require and explicitly state them in the require. Shouldn't this automatically parse bower/component/package.json files for this info, especially if you're touting the 'No Manifest' thing.
