or extend an existing repl session by typing `require('repl-edit').extend(global)`.
You can fire up a repl with editing capabilities by running `node-repl-edit`.

Commands
@ -63,6 +65,9 @@ capability to provide commands like `.edit` and `.stash <filename>`.

to an existing repl instead of having to run a separate binary that loads a repl.
