Wow, this is totally confusing and the dojo 1.8 documentation seems a complete clusterf**k around build layers. Anybody have a clue what's going on there?
In the build script example profiles, the example amd.profile.js has profile.layers["dojo/dojo"] and the tutorial follows this same syntax.
Besides the tutorial, in the 1.8 build documentation there is no mention of this kind of structure, but of profile.dependencies.layers[n].
The documentation also references non-AMD syntax and, just to add another "layer" of confusion, there's also a profile.dependencies.layers[n].dependencies.
Which should I be using? Is this actually documented anywhere with any consistency or clarity?
