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