27 * Unfortunately, the behavior this module has inherited is not one |
|
28 * of "get me information about file X or directory Y", but "tell me |
|
29 * what calling 'new File(X)' would do in Java". This includes |
|
30 * nonsense like manufacturing correct fake data for nonexistent |

31 * files. |
