Oh, that's nice.  Information (on the C implementation) is here:

The java-based version is called 'rhino'.

Some examples of the use of the interpreter (presumably as a standalone

Einstein himself said that God doesn't roll dice. But he was wrong. And
in fact, anyone who has played role-playing games knows that God
probably had to roll quite a few dice to come up with a character like
Einstein.  -- Larry Wall                                     C. Abney
