Correct, with respect to the kramdown project. :)

> kramdown (sic, not Kramdown or KramDown, just kramdown) is a free MIT-licensed Ruby library for parsing and converting a superset of Markdown. It is completely written in Ruby, supports standard Markdown (with some minor modifications) and various extensions that have been made popular by the PHP Markdown Extra package and Maruku.
