  28 Verify that rebuilds do not occur when SConsignFile(None) is used to
  29 put a .sconsign file in each directory and we subdvide the dependency
  30 tree with subsidiary *SConstruct* files in various subdirectories.
  31
  32 This depends on using content signatures for evaluation of
  33 intermediate Nodes. This relies on the default behavior
  34 being the equivalent of Decider('content').

  50 # Windows.  If we didn't do this, then running this script with
