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. | |
