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