-Managers are responsible for a certain aspect of the sytem.  It is a logical
-grouping of code relating to a portion of the system.  In general other
-components should be using the manager to make changes to the components that
-it is responsible for.
-
-For example, other components that need to deal with volumes in some way,
-should do so by calling methods on the VolumeManager instead of directly
-changing fields in the database.  This allows us to keep all of the code
-relating to volumes in the same place.
-
-We have adopted a basic strategy of Smart managers and dumb data, which means
-rather than attaching methods to data objects, components should call manager
-methods that act on the data.
-
-Methods on managers that can be executed locally should be called directly. If
-a particular method must execute on a remote host, this should be done via rpc
-to the service that wraps the manager
-
-Managers should be responsible for most of the db access, and
-non-implementation specific data.  Anything implementation specific that can't
-be generalized should be done by the Driver.
-
-In general, we prefer to have one manager with multiple drivers for different
-implementations, but sometimes it makes sense to have multiple managers.  You
-can think of it this way: Abstract different overall strategies at the manager
-level(FlatNetwork vs VlanNetwork), and different implementations at the driver
-level(LinuxNetDriver vs CiscoNetDriver).
-
-Managers will often provide methods for initial setup of a host or periodic
-tasksto a wrapping service.
-
-This module provides Manager, a base class for managers.
+Base class for managers of different parts of the system
