-- Source interface AlpineTransaction came from file AlpineTransaction.bcd,
-- which was created on 7-Jun-83 12:00:08 PDT with version stamp 117#174#6244074703
-- from source of 2-Apr-83 13:52:07 PST.
-- The RPC stub modules for AlpineTransaction are:
-- AlpineTransactionRpcControl.mesa;
-- AlpineTransactionRpcClientImpl.mesa;
-- AlpineTransactionRpcBinderImpl.mesa;
-- AlpineTransactionRpcServerImpl.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].
