+--------
+
+These playbooks are used to select a minimal subset of the roles included in
+the base playbooks.
+
+It will do nothing else than what is explicitly necessary for any job to run
+properly.

+      A subset of what the 'base' job provides: the absolute minimum considered
+      required to run for any one job.
+      It doesn't set up cached git repositories, will not set up mirrors,
+      doesn't validate the node, etc.
+      It is meant to be used, amongst other things, to test roles and
+      playbooks that would otherwise be included by default as part of the
+      'base' job.
+      These tasks, if required, can be included by the dependant jobs
+      themselves on a need basis.
