Glad to hear you got this far. Consider using something like this:
#! /bin/sh
#|
exec racket -tm "$0" ${1+"$@"}
|#
#lang racket
(provide
main)
(define main
(case-lambda
[(the-mandatory-argument . others)
(displayln
`(the-mandatory-argument:
,the-mandatory-argument
,(string? the-mandatory-argument)))
(displayln
`(others:
,others
,(length others)))
#true]
[() (displayln '(help, I need somebody, help))]))
I prefer this for simple scripts. Here are some interactions:
$ ./manage hello world, how are you doing
(the-mandatory-argument: hello #t)
(others: (world, how are you doing) 5)
#t
$ ./manage
(help (unquote I) need somebody (unquote help))
