It is great to see that Spud (a.k.a Matt Quail) is starting to get involved in open-source development, including Checkstyle. Matt is easily one of best developers I have ever come across in my career. So good in fact, he claims to have read the "Java in a Nutshell" book the night before I interviewed him as a graduate. To this day, he was one of the best Java programmers I interviewed.

The real irony is that when Matt started work, I got him to develop the predecessor to Checkstyle that used ANTLR. Over the course of a few weeks, involving extensive reviews, Matt produced a great little application that ended being used by our sponsor company site. His reward was to then spend a couple of weeks fixing all the errors the tool found in the software the team had written over the last six months (this included Javadoc:-).
