Root directory contents:
  - index.json: Describes the repository, including it's name, description, available channels, the system for which it provides packages, etc.
  - news: Contains news items. The latest news will be shown to the user when they next refresh their package database.
  - pool: Contains all the raw package files. If multiple channels provide the same package version/arch, both will point to the same package file within the pool.
  - channel: The channels that this repository provides.


/pool directory contents:
  - One directory for each letter of the alphabet, plus an extra set of directories for each letter of the alphabet prefixed with 'lib'.
    When a package is added to the repository, it is stored in one of these subdirectories. Which one depends on the first letter of the package name.
