Yes, it does, but what it does is call a driver in that language in its own
process (using the Java equivalent of fork) so there is no language
compatability issue. So, for example, there's a Java version of FIT,
there's a .NET version of FIT, there's a Python version of FIT,
and so forth. To invoke the Python versions, Fitnesse builds a
command something like:

Python FitFilter.py <path stuff> <working directory>

and passes it the HTML on its stdin, getting the result HTML
by reading the stdout and stderr.
