-"""Script to cleanup symlinks created from setup_links.py.
-
-Before 177567c518b121731e507e9b9c4049c4dc96e4c8 (#15754) we had a Chromium
-checkout which we created symlinks into. In order to do clean syncs after
-landing that change, this script cleans up any old symlinks, avoiding annoying
-manual cleanup needed in order to complete gclient sync.
