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