// Add ArtServicePointer specializations for LArSoft services so they
// can be accessed from the Root command line.
//
// The providers listed here may be accessed via provider type instead
// of service type.
//
// Usage example:
//   root> gSystem->SetBuildDir(".aclic");
//   root> gSystem->AddLinkedLibs(gSystem->ExpandPathName("$DUNETPC_LIB/libdune_ArtSupport.so"));
//   root> gSystem->AddLinkedLibs(gSystem->ExpandPathName("$DUNETPC_LIB/libdune_LarsoftServiceAccess.so"));
//   root> .L $DUNETPC_INC/dunecore/ArtSupport/ArtServiceHelper.h+
//   root> .L $DUNETPC_INC/dune/LarsoftServiceAccess/LarsoftServiceAccess.h+
//   root> ArtServiceHelper& ash = ArtServiceHelper::load("standard_reco_dune35tdata.fcl");
//   root> ChannelGroupService* pcgs = ArtServicePointer<ChannelGroupService>();
//   root> pcgs->print();
