clang-format binaries now come with every Chrome checkout!
Unfortunately, your depot_tools scripts tried to find clang-format binaries
in your Chrome checkout, but failed. This is expected if you haven't synced
since the binaries were added.
'git cl format' will probably not work until you sync your Chrome tree.
Sorry about that.
Contact [email protected] if you have any additional questions.\n\n'''
