I just went looking for the source for the dlang.org overview page, and found [this](https://github.com/dlang/dlang.org/blob/master/overview.dd).

I've seen and used a lot of markup formats, but have never run across this. What format is it? Also curious: for what reasons was it chosen over a more customary markup?

Thanks.

When D was first created there was no clear documentation solution (as far as I know. I was not a programmer back then), so Walter invented DDOC. Actually it's a general text macro system and is not markup language or a documentation generation system, which may be why it seems so strange if you're used to stuff like javadoc/doxygen/etc.
