Hi All,

(I'm cross-posting this from StackOverflow) 
http://stackoverflow.com/q/34837318/24172

I have this code:

(define s1 "aoeu")

(define command
  (command-line
   #:usage-help s1
   #:args (op) op))

It fails with "command-line: #:usage-help clause contains non-string."

If I replace the reference to s1 with an actual string (eg "aoeu") then it 
works just fine. I would like to build up that string (s1 in this example) 
dynamically, but I can't figure out how to do that.
