// $Log: IncludePage.php,v $
// Revision 1.27 2004/11/17 20:07:18 rurban
// just whitespace
//
// Revision 1.26 2004/09/25 16:35:09 rurban
// use stdlib firstNWordsOfContent, extractSection
//
// Revision 1.25 2004/07/08 20:30:07 rurban
// plugin->run consistency: request as reference, added basepage.
// encountered strange bug in AllPages (and the test) which destroys ->_dbi
//
// Revision 1.24 2004/02/17 12:11:36 rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.23 2003/03/25 21:01:52 dairiki
// Remove debugging cruft.
//
// Revision 1.22 2003/03/13 18:57:56 dairiki
// Hack so that (when using the IncludePage plugin) the including page shows
// up in the BackLinks of the included page.
//
// Revision 1.21 2003/02/21 04:12:06 dairiki
// Minor fixes for new cached markup.
//
// Revision 1.20 2003/01/18 21:41:02 carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
//
// For emacs users
// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
// c-hanging-comment-ender-p: nil
