installable through a Package Control channel

repository.json describes vDiff itself; "tags": true means a release is a
pushed git tag. channel.json is the file users add to their "channels"
setting - it holds nothing but repository URLs, so packages added to it
later reach existing users without them changing anything.

The two are easy to confuse: Package Control rejects a file under
"channels" unless it has a top-level "repositories" key, so a repository
file belongs in "repositories". The README spells that out.
