We do not want every developer to have to build clang, and so we store pre-built binaries in a Google Cloud Storage bucket and retrieve them via gclient hooks.
To roll new versions of the binaries, you need to have write access to the chromium-tools-traffic_annotation bucket. If you don't, contact the OWNERS list in this folder, otherwise run:

and land the resulting CL.
The following two lines will be updated by the above script, and the modified README should be committed along with the updated .sha1 checksums.
