Today we have something special for all you coders: we're releasing one of our most widely-used internal development tools. We call it "Protocol Buffers." It's the way we encode almost any sort of structured information which needs to be passed across the network or stored on disk. We thought Protocol Buffers might be useful to other people, too, so we've decided to release it as open source software. Check out the details on the Google Open Source Blog, or head directly to the project page on Google Code.
