/*
 * Package Operations:
 * -------------------
 * - Builds a catalog of file information from a directory tree rooted at a specified path.
 * - Stores each filename and path only once.
 * - Displays filenames and paths of duplicate files found in the catalog.
 * - Finds all files in the catalog containing a specified text string.
 * - Supports repeated queries for files containing specified text after building catalog.
 *
 * User Interface:
 * - Executive.exe path [/s][/a][/d][/f<text>][/q][/c][/h][/?]
 *   s, // recurse into subdirectories
 *   a, // show all files
 *   d, // report duplicates
 *   f, // find text
 *   q, // query for text at end of execution
 *   c, // display commandline arguments - used for testing
 *   h  // display usage message
 *   ?  // display usage message
 * Note: path must be first argument on command line.  There are no other placement constraints.
 *
 * Required Files:
 * ---------------
 * Executive.cpp, Catalog.h, Catalog.cpp, DataStore.h, DataStore.cpp, Display.h, Display.cpp,
 * FileMgr.h, FileMgr.cpp, FileSystem.h, FileSystem.cpp, Utilities.h, Utilities.cpp
 *
 * Build Process:
 * --------------
 * From the Visual Studio Developer's Command Prompt:
 * devenv VSHelp.sln
 * Note:
 *   Most of these packages use the Utilities built as a static library or dll.
 *   You may have to run devenv VSHelp.sln twice to successfully build the 
 *   Executive.
 *
 * Maintenance History:
 * --------------------
 * - Ver 1 : 1 Mar 2015
 *   first release
