-cipolate- and -csipolate- (SSC) are user-written commands. Please
remember that you are asked to explain where user-written commands you
refer to come from.

That said, all the hard work here in -csipolate- is done by official
Mata functions.

I don't see any obvious reason why this shouldn't work. You could try
sending me the data privately to check, but I am going off-line now
and will not be accessible for some hours.
