How to build documentation for ROS2 packages?
Wondering how, e.g. rclpy, got it's documentation built (you can find it's crystal docs here so I can build documentation for submitted packages.
There is nothing on the build farm indicative of a doc job, nor is there anything special of rclpy's package.xml apart from a dependency on sphinx.
Additionally, does the ros index always expect to be pointed at https://docs.ros2.org for apidocs?
