+`lmt` is primarily authored by Dave MacFarlane ([@driusan](https://github.com/driusan/)). Bryan Allred ([@bmallred](https://github.com/bmallred/)) improved the
+parsing code to include the metadata in the code block header rather than a
+rendered markdown header. [@mek-apelsin](https://github.com/mek-apelsin/)
+wrote the patch to include pragmas for line numbers, and Dave Abrahams
+([@dabrahams](https://github.com/dabrahams/)) wrote the demo of features in
+this README, making it more user-focused (it previously dove straight into
+implementation.)
