For extra read-eval-print loop support, evaluate @REQ[xrepl] Assuming that you have Editline installed,@margin-note*{To use GNU

@; FIXME: probably needs revisions, and questionable whether readline
@; should be mentioned by itself. One thing to consider is that with
@; readline it's possible to pretend that the whole thing is one
@; session, whereas xrepl changes the prompt.
If you want @emph{just} readline support in @exec{racket}, evaluate
@REQ[readline], instead, and then use @racket[(install-readline!)] to
adjust @filepath{~/.racketrc} to load @racketmodname[readline].
Readline is not needed if you're using @racketmodname[xrepl], if
you're running a shell inside Emacs, or if you're on Windows and use a
@exec{cmd} window.
