3# Purpose:
4#  This script is responsible for determining the owner of a gerrit
5#  commit, verifying they are within an approved gerrit group, and
6#  then updating gerrit with that verification info.
7#
8# Note: It is assumed this script is run as a part of a jenkins job triggered
9#       by the gerrit plugin. Therefore it assumes certain env variables
10#       provided by that plugin are avialable (i.e. GERRIT_PROJECT, ...)
11#
12# Required Inputs:
13#  SSH_KEY:  Path to private ssh key used to post messages to gerrit
