Gruber also lies about having invented markdown, which was actually invented by Aaron Swartz in 2002 (http://www.aaronsw.com/2002/atx/intro.html). Gruber just wrote a little perl script called Markdown.pl in 2004, but after Swartz's suicide in 2013, he pretended that he had come up with the whole thing, and has been using it to market himself ever since. Truly repugnant behavior.
