With it, you can automatically launch differents builds, changing the name,
the platform, the language and even constant values for each one. It is
designed for people that need to build many different binaries (different
platforms, localized, demo/light versions…) from a single source project

version 1.2.8 fix a bug on Classic launching RBulk with REALbasic already
opened, and adds Code debugging features (borrowed from Project Cuisinart,
