%description
Converts ROS messages to and from ASN.1-encoded ETSI ITS messages.

This ROS 2 package provides a Converter component node based on
rclcpp_components that bridges between ROS message types and the ETSI ITS
ASN.1 coding layer. It is part of the etsi_its_messages framework developed
by ika-rwth-aachen.
