ros-tf2-msgs - 0.7.7-3 main

This package is part of Robot OS (ROS). tf2 is the second generation
of the transform library, which lets the user keep track of multiple
coordinate frames over time. tf2 maintains the relationship between
coordinate frames in a tree structure buffered in time, and lets the
user transform points, vectors, etc between any two coordinate frames
at any desired point in time.
