| 11 | |
| 12 Before 177567c518b121731e507e9b9c4049c4dc96e4c8 (#15754) we had a Chromium | |
| 13 checkout which we created symlinks into. In order to do clean syncs after | |
| 14 landing that change, this script cleans up any old symlinks, avoiding annoying | |
| 15 manual cleanup needed in order to complete gclient sync. | |
