Snapshots, Data and Indexes
---------------------------
Snapshot, Data and Index files are cached in the sub-directories ``snapshots``,
``data`` and ``index``, as read from the repository.

------
Whenever a cache directory for a repo is used, that directory's modification
timestamp is updated to the current time. By looking at the modification
timestamps of the repo cache directories it is easy to decide which directories
are old and haven't been used in a long time. Those are probably stale and can
be removed.
