| <p> |
| The high level wrapper class RegEx is now deprecated and does not form |
| part of the regular expression standardization proposal. This type still |
| exists, and existing code will continue to compile, however the following |
| documentation is unlikely to be further updated. |
| </p> |

| <p> |
| The class RegEx provides a high level simplified interface to the regular |
| expression library, this class only handles narrow character strings, and |
| regular expressions always follow the "normal" syntax - that |
| is the same as the perl / ECMAScript synatx. |
