Binary package “topic-tools” in ubuntu lunar

Tools for messing with Robot OS topics

 This package is part of Robot OS (ROS). It contains tools for directing,
 throttling, selecting, and otherwise messing with ROS topics at a
 meta level. None of the programs in this package actually know about
 the topics whose streams they are altering; instead, these tools deal
 with messages as generic binary blobs. This means they can be applied
 to any ROS topic.
