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. |
