Here is a patch (against master) adding babel support for evaluating
stata code. As discussed in a previous thread[1] there is a lot of
work that should be done to clean it up and make it more useful. It
does work for basic code evaluation, so I'm submitting it here in the
hope that others find it useful.

Best,
Ista
