Seems like no one is having this problem but me, but where does one find the module location and documentation for the various Dojo modules? For example, the examples give the location of the xhr module at dojo/_base/xhr, but upon scouring the documentation I can't find anything about the xhr module or any module really. Only way to find it is google but that seems counter productive for learning, well, anything.
The xhr documentation is available as part of the Dojo reference guide under the Documentation section of Dojo's site. The landing pages could be laid out a lot better. Your suggestions are welcome. There's a link for feedback at the bottom of most documentation pages.
