My contribution to Gnome is fairly limited and of very mild importance. I did not help Havoc with Inti because Havoc was working full-time on it, with a very tight schedule, and I could only contribute on my free time. So I wouldn't be of much help. The main reason, however, was simply that I wanted to get back working on Rosegarden, and getting involved in yet another toolkit would certainly drive me further away from this. I do read it daily, and have contributed an article two years ago.
Corrections are welcome.
Anyway, here goes. However, I feel that the series of events which led to this is worth telling a little about. The problem though was that Havoc had to provide a solution on which he had complete control, since it would be proposed to customers. Mostly in the preprocessor, among others. I'm certainly among the first ones to blame for these.
