| 2 library. While this library started out as a copy of PCRE, many of the | |
| 3 features of PCRE have been removed. This library now supports only the | |
| 4 regular expression features required by the JavaScript language | |
| 5 specification, and has only the functions needed by JavaScriptCore and the | |
| 6 rest of WebKit. | |
