| * Revision 1.2 1999/11/30 21:16:25 roddey |
| * Changes to add the transcode() method to DOMString, which returns a transcoded |
| * version (to local code page) of the DOM string contents. And I changed all of the |
| * exception 'throw by pointer' to 'throw by value' style. |
| * |
| * Revision 1.1.1.1 1999/11/09 01:09:11 twl |
