Protobuf Global Extension Registry

This file contains a global registry of known extensions for descriptor.proto, so that any developer who wishes to use multiple 3rd party projects, each with their own extensions, can be confident that there won't be collisions in extension numbers.

If you need an extension number for your custom option (see custom options), please send us a pull request to add an entry to this doc, or create an issue with info about your project (name and website) so we can add an entry for you.
