RBulk Builder is a Batch Building companion for the REALbasic application.

With it, you can automatically launch different 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 file.
