Robots.txt Syntax Checker

I was checking the robots.txt file of a client today, and it was far more complicated than normal, so I went looking for an automated syntax checker.

I found this one from Motoricerca, (an Italian SEO company) and can recommend it: Robots.txt Syntax Checker (it's in English).

I like it so much I'm adding a link to it from my robots.txt generator.
