[racket] extract text?

I once wrote a script that does that -- you can find it at
barzilay.org/hacks.html -- but it might need some dusting.  It
precedes `wxme-port->whatever', and does some more work in an attempt
to produce some text that is close to the original wxme file.

But if you're using the handin server, then you can put some flags in
the checker files and it will create a text versions whenever a file
is submitted.  That makes things much more convenient, since you can
even make it reject submissions with non-textual items, if you want to
be able to have a text file that is exactly the same as the student
submissions.
