[racket] Making a section optional in Scribble

That's about right but you want your conditional to produce some element. 

In HtDP/2e, I use things like this all the time: 

  @(if draft? @bold{Draft Release} @bold{Stable Release})

where draft? is 

 @(define draft? (or (getenv "DRAFT") (is-draft?)))

that is, the flag is determined by either the environment or a command-line flag that is-draft? checks.
