   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.
