[ros-users] Nodelet based image pipeline

[Tully Foote]

I agree that standardizing the usb camera support is a great thing to do.
In the short term adding a nodelet manager into any node is trivial all you
have to do is instantiate a nodelet::Loader class.

The main for the nodelet manager looks like this:
{{{
  if (command == "manager")
  {
    ros::init (argc, argv, "manager");
    nodelet::Loader n;
    ros::spin();
  }
}}}
