32// cortex::NodeManager::AddOnHost.h
33// * PURPOSE
34//   Provides an interface to a separate BApplication whose
35//   single responsibility is to launch nodes.
36//   NodeManager-launched nodes now run in a separate team,
37//   helping to lower the likelihood of a socially maladjusted
38//   young node taking you out.
