Commit 6d31cb was an internal reorganization of google repository
that should have resulted in no change. Due to a bug in our export
process it deleted several files in third_party.

+### Updating the jar binary
+
+1. Go to http://search.maven.org/
+2. Search for g:"com.google.protobuf"
+3. Download the "jar" link from protobuf-java and put them in `<Bazel tree>/third_party/protobuf/<version>`
+
+* * *
+### Updating `protobuf.bzl` and the `src/` directory:
+
+1. `git clone http://github.com/google/protobuf.git`
+2. `git checkout <tag or commithash>` (e.g. `v3.0.0` or `e8ae137`)
+3. `mkdir -p third_party/protobuf/<version>/src/google` in the root of the Bazel tree.
+4. `cp -R <root of protobuf tree>/src/google/protobuf third_party/protobuf/src/google`
+5. Update the rules in `third_party/protobuf/BUILD` with the rules in the protobuf repository.
+
+Finally, update the rules:
+
+1. Add a BUILD file to `third_party/protobuf/<version>/`. Use the BUILD file
+   for the previous version as a template. Update the `cc_library` rules to
+   match the rules in the BUILD file in the protobuf repository. Also copy
+   `protobuf.bzl` from the protobuf repository into
+   `third_party/protobuf/<version>/`.
+2. Modify `third_party/protobuf/BUILD` to point to the new rules.
+3. Delete the old version of protobuf.
