# A command line interface to find a single crash session stacktrace in Crashlytics.
# This is impossible by using their web dashboard interface.
#
# Usage: `ruby dump_crashlytics_session.rb BEARER_TOKEN PROJECT_ID SESSION_ID`
#
# The session ID is [`[CLSReport identifiter]`](https://docs.fabric.io/appledocs/Crashlytics/Classes/CLSReport.html#//api/name/identifier).
# The project ID is an unique ID for each application, you can find in Fabric settings page.
# The bearer token is an authentication token, you can find it in web browser inspector on Fabric pages.
