+// This script acts as a trigger script for the main ngraph-unittest.groovy
+// Jenkins job.  This script is part of a Jenkins multi-branch pipeline job
+// which can trigger GitHub jobs more effectively than the GitHub Pull
+// Request Builder (GHPRB) plugin, in our environment.
+
+// The original ngraph-tf-unittest job required the following parameters.  We
+// set these up below as global variables, so we do not need to rewrite the
+// original script -- we only need to provide this new trigger hook.
+//
+// Parameters which ngraph-unittest uses:
+String  PR_URL = CHANGE_URL
+String  PR_COMMIT_AUTHOR = CHANGE_AUTHOR
+//ORIG: String  JENKINS_BRANCH = "master"
+String  JENKINS_BRANCH = "chrisl/ngraph-bridge"
+
+// Constants
+JENKINS_DIR = 'jenkins'
