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