For projects that need to use RAD's headless capabilities (or, even better, BU) as the build system. This causes Hudson to invoke RAD/BU with the given targets and options. Any non-zero exit code causes Hudson to mark the build as a failure.
Hudson supplies some environment variables that can be used from within the build script.
To know more about RAD's headless features, please refer to the RAD 7.0 Infocenter or to the RAD 7.5 Infocenter.
