Hi all,

Is it possible to run the racket handin-server from a remote Linux shell, 
without setting up an X forwarding session?  When I attempt to start it using 
"gracket-text -l handin-server" as specified in the docs, I get an error about 
not having a display available; the error appears to stem from the dependency 
on racket/gui/base.  (My plan was to run it on a server that the students can 
access from home whenever, something my workstation & network at school won't 
allow.)

Or perhaps am I fundamentally misunderstanding the way the handin server is 
supposed to work?  (My mental model is: students submit files to server, 
instructor downloads a copy of the directory, and runs/checks the submissions 
locally.)

By the way, this reminded me:  is there a straightforward way to collect the 
test cases from a submission, and run them on code that I've written?

Best,
Jordan
