===================================================================
Google doesn't allow using Chrome's API keys in Chromium builds and
strongly recommends against doing so. These OAuth 2 credentials are
taken from publicly available sources, but their fitness for use in
Chromium builds is not warrantied.
===================================================================

!!! Use these keys to reactivate Sync in Chromium at your own risk;
    they are extremely likely to stop working in the (near) future.

$ grep oauth2 ~/.config/chromium-flags.conf
--oauth2-client-id=77185425430.apps.googleusercontent.com
--oauth2-client-secret=OTJgUOQcT7lO7GsGZq2G4IlT

Note: The above works on Arch Linux because of its custom launcher,
      plus a patch to reuse --oauth2-client-{id,secret} for setting
      GOOGLE_DEFAULT_CLIENT_{ID,SECRET} similar to environment vars.
