00001 /* This is the public header file for JavaScriptCore's variant of the PCRE 00002 library. While this library started out as a copy of PCRE, many of the 00003 features of PCRE have been removed. This library now supports only the 00004 regular expression features required by the JavaScript language 00005 specification, and has only the functions needed by JavaScriptCore and the 00006 rest of WebKit. 00007 00008 Copyright (c) 1997-2005 University of Cambridge 00009 Copyright (C) 2002, 2004, 2006, 2007 Apple Inc.
