HTML5 Binaries Missing from Source Builds

I notice that binary versions of the engine contain an Engine/Binaries/HTML5 directory, which contains a ton of precompiled *.bc files. However, Source builds don’t seem to create these files, even after running Setup, GenerateProjectFiles, etc.

Is there any way to force generation/saving of these compiled HTML5 binaries when using a Source build?

To self-answer my old question: To generate the relevant HTML5 binaries, you just have to build the engine from within Visual Studio with the Development+HTML5 and/or Shipping+HTML5 configurations (depending on what type of HTML5 project you’re trying to export, Development or Shipping.)
