-"""Utility to duplicate a config in some subset of our GM expectation files.
-
-Created for http://skbug.com/2752 ('split existing "gpu" GM results into "gl"
-and "gles"')
-
-Run with -h to see usage.
-
-Example command lines:
-  copy_config.py gl gles '.*Mac10.7.*'
-
-TODO(epoger): Once https://codereview.chromium.org/397103003/ is committed,
-we should add a unittest.  Until then, we can test this as follows:
-
-OLD=expectations/gm && NEW=/tmp/expectations && \
-  rm -rf $NEW && \
-  cp -a $OLD $NEW && \
-  gm/copy_config.py 8888 8888-copy '.*Mac10.7.*' \
-    --expectations-root $NEW && \
-  diff --recursive $OLD $NEW
