  Module Operations: 
  ==================
  The class Scanner provides methods to scan files, recursively
  opening all included local header files.  It currently provides
  "hard-wired" processing in the members:
  - doNonDestructiveProcessing() processes each SemiExp encountered
    in the current file.
  - doFileProcessing(file) processes file level information.
  To use scanner you have to either put your processing into these
  members, or better, design plug-in processing, so the module can
  become reusable.

  Public Interface:
  =================
  Scanner scanr;
  scanr.doRecursiveScan(file);
  
  Build Process:
  ==============
  Required files
    - RecScan.h, RecScan.cpp,
      FileInfo.h, FileInfo.cpp,
      WinTools.h, WinTools.cpp,
      SemiExpression.h, SemiExpression.cpp,
      Tokenizer.h, Tokenizer.cpp

  Build commands (either one)
    - devenv Project1HelpS06.sln
    - cl /EHsc /DTEST_RECSCAN RecScan.cpp FileInfo.cpp WinTools.cpp\
                              SemiExpression.cpp Tokenizer.cpp

  Maintenance History:
  ====================
  ver 1.0 : 06 Feb 06
  - first release
