negative.code: *      into a ROOT macro (C++ file).
  *
  *  To use this conversion program (in $ROOTSYS/bin),
  *        g2root [-f <map_names>] <geant_rzfile> <macro_name> [lrecl]
  *  run g2root without parameters to see the usage info.
  *
  *  for example
  *        g2root na49.geom na49.C
  *  will convert the GEANT RZ file na49.geom into a ROOT macro na49.C
  *
  *  The default value for lrecl is 1024. The parameter lrecl must be specified
  *  if the record length of the Zebra file is greater than 1024.
  *
  *  You can use <map_names> file to rename generated TNode's.
  *  See an example of that file in the commented section below.
