-"""rebase.py: standalone script to batch update bench expectations.
-
-    Requires gsutil to access gs://chromium-skia-gm and Rietveld credentials.
-
-    Usage:
-      Copy script to a separate dir outside Skia repo. The script will create a
-          skia dir on the first run to host the repo, and will create/delete
-          temp dirs as needed.
-      ./rebase.py --githash <githash prefix to use for getting bench data>
