libbond-dev 1.8.6-10 (armhf binary) in ubuntu mantic

 This package is part of Robot OS (ROS). This is the 'bond' process state
 machine library development files.
 .
 Bond is a mechanism for checking when another process has
 terminated. A bond allows two processes, A and B, to know when the
 other has terminated, either cleanly or by crashing. The bond remains
 connected until it is either broken explicitly or until a heartbeat
 times out.
