This the source for the Racket package: "readline-gpl".
This package lets you use GNU's libreadline rather than libedit for the readline collection.
This is useful if you don't have libedit on your system or if you need features that are only in readline.
To install:
raco pkg install readline-gplContribute to Racket by submitting a [pull request], reporting an [issue], joining the [development mailing list], or visiting the IRC or Slack channels.
