Ah yes I see now. So everyone understands what is happening now I have
Z/main.rkt
#lang Z/private
(require racket/base)
(provide (all-from-out racket/base))
Z/private/lang/reader.rkt
#lang s-exp syntax/module-reader
Z/private/main
#:language-info #(Z/private/runtime configure 'dont-care)
Z/private/main.rkt
#lang racket/base
(provide (all-from-out racket/base))
Z/private/runtime.rkt
#lang racket/base
(provide configure)
(define (configure . args)
(printf "called configure with ~a\n" args)
#f)
$ PLTCOLLECTS=`pwd`:$PLTCOLLECTS racket -Iq Z
Welcome to Racket v5.1.3.6.
called configure with ((quote dont-care))
procedure application: expected procedure, given: #f; arguments were:
'configure-runtime '()

Now of course I have to provide the right thing from `configure'.
