Couldn't agree more.

GNU Gretl, a sleek intro- to intermediate econometrics program, actually has
interfaces to both x12a and tramo-seats, the latter being more of a problem
as it is not available in source from the Bank of Spain. Gretl works on (at
least) Windows, OS X and Linux.  I maintain the Debian package too.

Would be nice if someone looking for a decent code project took Census' x12a
sources and brought the dreadful text-file based interface forward into this
century by linking it to R.
