Set up an Upspin server backed by Google Drive

Overview

The purpose of this document is to explain how to deploy an Upspin server on a Debian or Ubuntu based machine - which can be a Raspberry Pi - and, optionally, use Google Drive to back the data.

Effectively, this will give you all the nifty advantages Upspin gives you in terms of file sharing without requiring a costly server.

a := make(chan int) # this gives an unbuffered channel

// read from channel a
