Use triple quotes around your string when you need it to contain
newlines:

"""Hello
world.
"""

Have a look at the registry file in the jython directory (where
jython.jar is), and look for the readline option.
It needs a java class that accesses the native readline lib
that you may have to download iirc.

There is also a simple Console.py in the demo dir that has
an up arrow which is good enough for me.

Ype
