This won't work, unfortunately.  enter! takes in "module paths", and
according to the rules, if it's a plain string, it must be a relative
path string.  See the "rel-string" stuff in
http://docs.racket-lang.org/reference/require.html.

To make this work, John can do:

    (enter! (file "C:\\indexing\\serve.rkt"))

in which case since we're telling Racket it's ok to use a
platform-dependent path, Racket will acquiesce.



Alternatively, he can change the current directory first:

    (current-directory "C:\\indexing")

after which:

    (enter! "serve.rkt")

should be fine, because "serve.rkt" is relative to the current directory.



But if we're already in DrRacket, why use the enter! stuff to begin
with, when we've got the Run button?
