SCO's lawsuit against IBM: overview

I have stopped working on this document. It reflects the situation roughly in October 2003. Since then, I have become convinced that SCO's claims are bogus, and that they are acting either dishonestly or with a staggering lack of understanding. There's nothing I can do to address either of these issues.

I have written a detailed analysis of SCO's attacks against free software, notably IBM and Linux. On this site, you'll find my comments about the following topics:
