| 1 | /* Getopt for Microsoft C | 
| 2 | This code is a modification of the Free Software Foundation, Inc. | 
| 3 | Getopt library for parsing command line argument the purpose was | 
| 4 | to provide a Microsoft Visual C friendly derivative. This code | 
| 5 | provides functionality for both Unicode and Multibyte builds. |
