//
// NOTE - chain needs to be declared global so for StHbtEventReader
// Modified from StRoot/StMuDstmaker/COMMON/macros i.e. initially
// written by Frank Laue.
//
// Extend to account for production purposes.
// Arguments are
//      mode             bitmaks 
//                       bit 1 0x1   CMuDST always on regardless of 1st bit
//                       bit 2 0x2   EMC 'MuDST' ON/OFF (different from EMC branch in CMuDst)
//                       bit 3 0x4   RICH mode ON/OFF    
//                       bit 4 0x8   V0Finder processing during MuDst production
//
//      nevents
//      path             Path where the InputFile resides ; "-" for local
//      InputFile        Should be an event.root file
//      OutputDirectory  Optional output directory (does not fully work)
