# This script is designed to detect when a patchset uploaded to Gerrit is
# 'identical' (determined via git-patch-id) and reapply reviews onto the new
# patchset from the previous patchset.

# Get usage and help info by running: ./trivial_rebase.py --help
# Documentation is available here: https://www.codeaurora.org/xwiki/bin/QAEP/Gerrit
