# Finds the latest Passenger crash log directory and prints its path.
# This tool is meant to make it easy to analyze local Passenger crash
# logs during debugging sessions. Instead of searching for the crash
# log directory path in the output and then copy-pasting that to the
# terminal, one can simply invoke one shell command:
#
#   less $(./dev/show-latest-crashlog-dir)/backtrace.log
#
# This will open the latest crash log's backtrace.log in 'less'.
