Notes:
This patch has been split up into 2 parts.
This first part only introduces the infrastructure
without exposing it to the user at all (no command line
option nor a repository configuration option).
The exposure to the user will be added in a later second
patch. This allows us some time in between to build all
the features we want without the requirement to be
functional.
