This fixes #23 for @parsoj by allowing a custom disclaimer to be specified via dependency injection modules. By making the disclaimer part of the dependency injection graph, it can come from anywhere. For example, if I was Donuts, I would have my own repository. I'd use an external http_archive() repository for Domain Registry. Then I would write my own Dagger @Component for each App Engine module. My Component would have a list of Dagger Modules, which I copied from the Domain Registry version. Then I would swap out ConfigModule with my own DonutsConfigModule, which provides the same values. So long as a method exists that @Provides @Config("whoisRegistry"), and the module containing it is listed in the @Component, the dependency injection graph becomes valid and complete for the whois package (provided other dependencies are met.) ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=128082921
