00028 //       Class : Win32ArgParser
00029 // Description : This class is used to parse the single command-line
00030 //               string provided by Windows into the standard argc,
00031 //               argv array of strings.  In this way it duplicates the
00032 //               functionality of Windows' own CommandLineToArgv()
00033 //               function, but it is also supports automatic expansion
00034 //               of glob filenames, e.g. *.egg is turned into an
00035 //               explicit list of egg files in the directory.
