is distributed under the GPL, not the LGPL, so they definitely can't be 
using a shared library interface to hook into it. So I'm guessing they use 
something like pexpect (it says J/Link on the website). I'm curious whether 
that's enough to keep Mathematica from being a derivative work in the GPL 
sense, although Wolfram's legal department's probably got that one covered.
