How do we know that the response is from Yukihiro himself? :) 2. Why is GPL license distributed with Ruby? How do we know which components are GPL based? 3. When ruby.h is included in a C++ application, almost all header files from the Ruby distribution get included, and if each one has different license associated with it, is there a clean way to extract non-GPL files so that one can link with Ruby in a commercial application?
