Today, I finished writing tests for the CTABLES procedure. Some code cleanup is necessary, then the last step is to finish writing the documentation for the manual. I'm almost done with that, too. It's possible that I could even have it ready for people to test before the end of the month.
At that point, I think it might be time to call the next PSPP release version 2.0, since multiple big features have been added since the 1.0 release.
