For extra read-eval-print loop support, evaluate @REQ[xrepl]
to enable Readline-based input---assuming that you have GNU Readline
installed on your system---and comma-prefixed meta-commands that
support exploration and development. To have @racketmodname[xrepl]
loaded by default, use the @xreplcmd{install!} command, which updates
your @filepath{~/.racketrc} to load @racketmodname[xrepl] whenever you
start @exec{racket} for interactive evaluation.
@margin-note{Unfortunately, for legal reasons related to GPL vs. LGPL,
@exec{racket} cannot provide Readline automatically.}

@; 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.

Assuming that you have Editline installed,@margin-note*{To use GNU
Readline instead of Editline, set the @envvar{PLT_READLINE_LIB}
environment variable or install the @filepath{readline-gpl} package.}
@exec{racket} by default supports line editing and comma-prefixed
meta-commands that support exploration and development. See
@racketmodname[xrepl] for more information.
