-// KeystoneGlue is an adapter around the KSRegistration class, allowing it to
-// be used without linking directly against its containing KeystoneRegistration
-// framework.  This is used in an environment where most builds (such as
-// developer builds) don't want or need Keystone support and might not even
-// have the framework available.  Enabling Keystone support in an application
-// that uses KeystoneGlue is as simple as dropping
-// KeystoneRegistration.framework in the application's Frameworks directory
-// and providing the relevant information in its Info.plist.  KeystoneGlue
-// requires that the KSUpdateURL key be set in the application's Info.plist,
-// and that it contain a string identifying the update URL to be used by
-// Keystone.
