Interesting thing about Mercury is that Prince [1] is written in it which is the only "browser" that supports the full print CSS spec and is widely used and considered the gold standard for converting HTML to PDF. Mercury was developed by the founders of Prince. So you probably have used content created in Prince which is built with Mercury. Pretty interesting to have such a successful product built with your own programming language that is also as complex as a web browser [2]. 1. https://en.wikipedia.org/wiki/Prince_(software) https://en.wikipedia.org/wiki/Prince_(software) 2. https://www.princexml.com https://www.princexml.com
