It gives you all the nice features like history with up arrow/down arrow
access, tab completion (I think), basically everything you get with a
mysql console, or python interactive mode, or bash. I understand that
Jython uses Java-Readline http://java-readline.sourceforge.net/, which
just JNI-wrappers the C library.

It's definitely very nice and would make the jscheme interpreter act
more like most commandline driven Linux tools.

Unfortunately, GNU readline is GPL licensed (as you might imagine). My
understanding is that there is a BSD licensed replacement
(http://sourceforge.net/projects/libedit/), but I don't know how active
or useful it is, and I don't know how well it works with Java-readline
(which itself is LGPL).=20
