The entire program is shown on the code tab. The HTML is shown in the HTML tab: as is common with backdraft programs, there's zero markup.

The actual code loaded has been compressed; if you would like to look at the source used in this application, including all backdraft and dojo modules, click here (warning: since the source version downloads lots of files, it takes longer to load. Rest assured, this is not a factor when developing on a local http server).
