[racket] Using Scribble to evalute code blocks in different runtimes

That's right for evaluation within Racket, but I think the question was
about calling external programs (that happen to implement other Lisp
dialects).

Here's an example that uses `system' and `verbatim' to show output from
`csi':

 #lang scribble/base
 @(require racket/system)

 @(define (show-system command [input ""])
    (define s (open-output-string))
    (parameterize ([current-output-port s]
                   [current-input-port (open-input-string input)])
      (system command))
    (verbatim (get-output-string s)))

 @show-system["csi -p '(+ 1 2)'"]
