Could you please 

i)  define 'replicate', and 

ii) cite any licenses to back up this claim, or simply show us what you
    find so confusing.

I suspect that you are misinterpreting this, and that tramo-seats is indeed
"simply" closed-source software that you can get re-distributed in binary
form (e.g. from the gretl website, see below), but not in source.

A couple of years ago I toyed with both the US Census' X12-ARIMA procedure
and its tramo-seats alternative by Maravall et al.  Given how atrociously
'1960s' the X12-ARIMA interface is, I toyed with building an R frontend given
that you get the Fortran code to X12-ARIMA straight from the Census site .
But then something else came up and I never pursued this ...

The closest I know to using x12 and/or tramo-seats from somewhat saner and
more modern software is via Allin Cottrell's gretl (cf http://gretl.sf.net).
And per my suggestion a few years back, Allin even hacked a 'gretl to R'
interface [ via mucking with ~/.Rprofile which isn't pretty but that is
another story ... ]

Hope this helps,  Dirk
