Here is an example of how to configure the mock component. This creates a number of mock chroot configurations for each platform with different sets of repositories. This makes it possible to ensure that you have built a package for a particular repository which will not have dependencies on packages which are covered by stronger license restrictions. (i.e. something built using a uoe mock chroot will not depend on anything in the inf repository).
