[racket] a couple of trivial Scribble questions

I put the first example in section 1.1 of the Scribble documentation in 
Help Desk into a file test.scrbl in DrRacket (5.1.1). I can run it, and 
nothing happens. Should something? (I'll accept "No" as an answer, but 
then what does the Run button do?) And shouldn't there be a Check Syntax 
button? I only see Run and Stop.

Also, when I render this file into PDF on the command line, there's a 
date. How do I get rid of it? In LaTeX, I'd just say \date{}.

Thanks. --PR
