-- Stub file TankMasterRpcClientImpl.mesa was translated on 16-Mar-83
-- 9:07:25 PST by Lupine of 18-Feb-83 11:25:52 PST.
-- Source interface TankMaster came from file TankMaster.bcd, which
-- was created on 16-Mar-83 9:07:11 PST with version stamp 176#227#36526563207
-- from source of 16-Mar-83 9:06:51 PST.
-- The RPC stub modules for TankMaster are:
-- TankMasterRpcControl.mesa;
-- TankMasterRpcClientImpl.mesa;
-- TankMasterRpcBinderImpl.mesa;
-- TankMasterRpcServerImpl.mesa.
-- The parameters for this translation are:
-- Target language = Cedar;
-- Default parameter passing = VALUE;
-- Deallocate server heap arguments = TRUE;
-- Inline RpcServerImpl dispatcher stubs = TRUE;
-- Maximum number of dynamic heap NEWs = 50, MDS NEWs = 50;
-- Acceptable parameter protocols = VersionRange[1,1].
