+"""Sliver manager API.
+
+This module exposes an XMLRPC interface that allows PlanetLab users to
+create/destroy slivers with delegated instantiation, start and stop
+slivers, make resource loans, and examine resource allocations. The
+XMLRPC is provided on a localhost-only TCP port as well as via a Unix
+domain socket that is accessible by ssh-ing into a delegate account
+with the forward_api_calls shell.
