# Given a directory with at least one bag file, find the filename with the
# latest timestamp (%Y-%m-%d-%H-%M-%S) in name and open it with `rqt_bag`.
# This is particularly useful given a directory of many rosbags that were
# created via `rosbag record` without an explicit filename.
# If the files were created with `rosbag record -o <name>`, then <name>
# will be appended with a timestamp, in which case the latest of *these*
# bags can be found with `./lastbag <name>`.
