Why didn't you just say that?

I'm taking this multiple linear regression course this semester, and I'm slightly annoyed by it. Rather than use software that some of us might have used before (SPSS, R, Matlab, etc), the instructor decided to use something that no one uses (including himself). Ok, experimental, I can deal with that. However, this software has absolutely no manual, user help site, message board, nothing. The textbook is supposed to act as a user guide, but is written in such a way that it is nearly impossible to find what you are looking for. Grr... throw me a bone here, people.
