It is in development. Started working on it last week. Still experimental. Thinking of changing the syntax a bit to be a little more intuitive. It's on github:

Will add a command line compiler and stuff soon. We are using it to generate documents at our startup. So it will be in active development for sometime.
I find that except for math I use a minimal amount of features of latex, but a lot of work and weird code to display simple things.
I just don't get why there isn't something that does a few things well and nothing else.
