+The ``--specs-..`` options specify instance policy on the cluster. Each
+option can have three values: ``min``, ``max`` and ``std``, which can
+also be modified on group level (except for ``std``, which is defined
+once for the entire cluster). Please note, that ``std`` values are not
+the same as defaults set by ``--beparams``.
+``--specs-cpu-count`` sets the number of VCPUs that can be used by an
+instance.
+``--specs-disk-count`` sets the number of disks
+``--specs-disk-size`` limits the disk size for every disk used
+``--specs-mem-size`` limits the amount of memory available
+``--specs-nic-count`` sets limits on the amount of nics used
