ADD any comments in this line and below.
  for multiple components in single executable, 
  include component info between Multi_Comp_Start
  and Multi_Comp_End, list the number of components(optional),
  and each component's relative processor_id in
  that executable world.  Up to 5 strings could also be 
  attached in the end to pass input and output file names 
  and some other info.  Processor overlap is
  allowed within each multi-component executable but 
  NOT within each multi-instance executable.
