| 1 /* This is JavaScriptCore's variant of the PCRE library. While this library | |
| 2 started out as a copy of PCRE, many of the features of PCRE have been | |
| 3 removed. This library now supports only the regular expression features | |
| 4 required by the JavaScript language specification, and has only the functions | |
| 5 needed by JavaScriptCore and the rest of WebKit. | |
