- /* 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.
