// This can be used to quickly generate a GDML file from a ROOT
// macro produced by hdds-root. The one line execution is something
// like:
//
// > root -b -q $BMS_OSNAME/src/hddsroot.C mkGDML.C
//
// This will automatically generate a file named "hddsroot.gdml" from
// the $BMS_OSNAME/src/hddsroot.C mkGDML.C file.
