Kenji Obata from XenoCode has just moved his build process to FinalBuilder -
“In just a few hours, I had the entire Xenocode build process running under FB. The IDE and scripting model is extremely intuitive and easy-to-learn (it earned a perfect score on my key usability measure, number of queries required into the manual -- zero).“
At the time FB only supported XenoCode 2004, but FB3.1 now supports XenoCode 2005 as well.
