wbcore-2/buildtools

This directory contains hashes of build tools used by Chromium and related
projects. The actual binaries are pulled from Google Storage, normally as part
of a gclient hook.

This directory also exists as a stand-alone git mirror at
https://chromium.googlesource.com/chromium/src/buildtools/.
That mirror exists so that the shared build tools can be shared between
the various Chromium-related projects without each one needing to maintain
their own versionining of each binary.

________________________
ADDING BINARIES MANUALLY

One uploads new versions of the tools using the 'gsutil' binary from the
Google Storage SDK:

https://developers.google.com/storage/docs/gsutil

There is a checked-in version of gsutil as part of depot_tools.

To initialize gsutil's credentials:

python ~/depot_tools/third_party/gsutil/gsutil config

That will give a URL which you should log into with your web browser.

Copy the code back to the command line util. Ignore the project ID (it's OK
to just leave blank when prompted).
