[racket] [slideshow/code] typesetting comments

I tried:

#lang slideshow

@slide[
  @t{Blah blah}]

but that gives me:
compile: unbound identifier in module in: @slide

Can you point me to the documentation for this syntax?
(@slide does not give any result in the Help desk search)

Thanks,

-- Éric
