rostopic contains the rostopic command-line tool for displaying
debug information about
ROS Topics, including
publishers, subscribers, publishing rate,
and ROS Messages. It also
contains an experimental Python library for getting information about
and interacting with topics dynamically. This library is for
internal-use only as the code API may change, though it does provide
examples of how to implement dynamic subscription and publication
behaviors in ROS.
