/*
  Module Operations: 
  ==================
  This module defines a console executive.  Its purpose is to provide
  a placeholder for command-line driven programs, like anal.  

  Public Interface:
  =================
  This Executive module provides services, not through a software
  interface, but through a set of command-line arguments,
  provided to allow a user to control the files analyzed and see
  the results of that analysis.

  Build Process:
  ==============
  Required files
    - ConsoleExec.cpp,
      ConfigureParser.h, ConfigureParser.cpp,
      ActionsAndRules.h, ActionsAndRules.cpp,
      Parser.h, Parser.cpp,
      SemiExpression.h, SemiExpression.cpp,
      tokenizer.h, tokenizer.cpp

  Build commands (either one)
    - devenv Project1HelpS06.sln
    - cl /EHsc ConsoleExec.cpp, ConfigureParser.cpp, ActionsAndRules.cpp \
               Parser.cpp SemiExpression.cpp Tokenizer.cpp

  Maintenance History:
  ====================
  ver 1.0 : 01 Feb 06
  - first release
