if you have to maintain an older application: If it was written with
the 2.1 version of Turbine, Torque was a part of Turbine then. It has
been decoupled in the 2.2 cycle and for the current release (2.3),
Turbine uses Torque in a few places (Security Service and Scheduler
Service) as OM layer for accessing database information.

Apart from this, Turbine offers you a facility to initialize Torque
when you start up a Turbine application (with the AvalonComponentService).

Your application can use Torque as an OM layer. Turbine itself uses
Torque only for the services mentioned above (and unfortunately in a
few method signatures due to historic reasons).

"Fighting for one's political stand is an honorable action, but re-
 fusing to acknowledge that there might be weaknesses in one's
 position - in order to identify them so that they can be remedied -
 is a large enough problem with the Open Source movement that it
 deserves to be on this list of the top five problems."
