Mplus
My good friend Levente is a professional stats geek. He uses a package called Mplus to do some kind of numerical voodoo.
Sometimes, Mplus produces output in a human-readable text format. It's pretty, as these things go, but sucks to manipulate unless you really enjoy copy & paste exercises. Here is some Perl to pull out sets of values using regular expressions and dump them to a very simple CSV file.
If this sounds useful, the attached tarball includes some sample configurations.
