CGSuite is a program for solving CGT problems written by Aaron Siegel et al.
V1.1 is the latest version. It was used to create most of the values on the No Pass Go Examples page.
V1 contains a solving tool for AntiAtariGo. It no longer contains general Go solving tools.
V0.7 contained tools for calculating the CGT value of general Go positions - although this was provided as an undocumented and buggy feature.
You can find it on sourceforge
