/////////////////////////////////
Supposedly you can create “modules” in Java9+ and thus, if we do that, it would
be:
~ jshell --module-path ~/modules --add-modules tinkerpop4.module
Finally, note the "/set feedback concise” option I set. You can design your own
feedbacks.

<http://cr.openjdk.java.net/~rfield/tutorial/JShellTutorial.html#defining-a-feedback-mode>
You can have a startup script and thus, users would do:
~ jshell tinkerpop-shell.jsh --module-path ~/modules

I say we don’t build a console for TinkerPop4.
JShell for Gremlin-Java
Groovysh for Gremlin-Groovy
Python for Gremlin-Python
…
Less code, less documentation, ...
Take care,
Marko.
