It's written in C++. /s I suspect it hasn't gotten a lot of widespread publication in English forums because it's from a University project from Japan so there aren't a lot of English-speaking contributors (there are only 9 contributors to the official repo). Additionally, it was only open sourced in 2014 so as an open source project it's pretty young.
