[racket] Help: Running racket programs from command line

Hello,

Can anyone please tell me how to process all the files in a directory.

This is what I am doing:

(check-progs (directory-list "/home/racket/progs"))

(define (check-progs flist)
  (if(list? flist)
     (if(null? (cdr flist))
        '()
        (check-progs (cdr flist)))
     (process (simple-form-path (car flist)))))


(define (process path)
  (local-require path)
  (local-require rackunit)
  (check-equal? (twice 2) 4)

Thanks in advance.
