00001 /* This is JavaScriptCore's variant of the PCRE library. While this library 00002 started out as a copy of PCRE, many of the features of PCRE have been 00003 removed. This library now supports only the regular expression features 00004 required by the JavaScript language specification, and has only the functions 00005 needed by JavaScriptCore and the rest of WebKit. 00006 00007 Originally written by Philip Hazel 00008 Copyright (c) 1997-2006 University of Cambridge 00009 Copyright (C) 2002, 2004, 2006, 2007 Apple Inc.
