-- Source interface AlpineVolume came from file AlpineVolume.bcd, which
-- was created on 7-Jun-83 11:44:51 PDT with version stamp 117#174#6244076013
-- from source of 2-Apr-83 13:53:20 PST.
-- The RPC stub modules for AlpineVolume are:
-- AlpineVolumeRpcControl.mesa;
-- AlpineVolumeRpcClientImpl.mesa;
-- AlpineVolumeRpcBinderImpl.mesa;
-- AlpineVolumeRpcServerImpl.mesa.
-- The parameters for this translation are:
-- Target language = Cedar;
-- Default parameter passing = VALUE;
-- Deallocate server heap arguments = TRUE;
-- Inline RpcServerImpl dispatcher stubs = FALSE;
-- Maximum number of dynamic heap NEWs = 50, MDS NEWs = 50;
-- Acceptable parameter protocols = VersionRange[1,1].
