// Revision 1.26 2005/11/14 22:33:04 rurban
// print ignored stoplist words
//
// Revision 1.25 2005/09/11 14:55:05 rurban
// implement fulltext stoplist
//
// Revision 1.24 2004/11/26 18:39:02 rurban
// new regex search parser and SQL backends (90% complete, glob and pcre backends missing)
//
// Revision 1.23 2004/11/23 15:17:19 rurban
// better support for case_exact search (not caseexact for consistency),
// plugin args simplification:
// handle and explode exclude and pages argument in WikiPlugin::getArgs
// and exclude in advance (at the sql level if possible)
// handle sortby and limit from request override in WikiPlugin::getArgs
// ListSubpages: renamed pages to maxpages
//
// Revision 1.22 2004/05/28 11:01:58 rurban
// support to disable highlighting
// example: s=ReiniUrban&hilight=0&noheader=1
//
// Revision 1.21 2004/04/18 01:11:52 rurban
// more numeric pagename fixes.
// fixed action=upload with merge conflict warnings.
// charset changed from constant to global (dynamic utf-8 switching)
//
// Revision 1.20 2004/02/28 21:14:08 rurban
// generally more PHPDOC docs
// see http://xarch.tu-graz.ac.at/home/rurban/phpwiki/xref/
// fxied WikiUserNew pref handling: empty theme not stored, save only
// changed prefs, sql prefs improved, fixed password update,
// removed REPLACE sql (dangerous)
// moved gettext init after the locale was guessed
// + some minor changes
//
// Revision 1.19 2004/02/26 04:27:39 rurban
// wrong limit notification
//
// Revision 1.18 2004/02/26 04:24:03 rurban
// simplify quiet handling by using PageList
//
// Revision 1.17 2004/02/26 04:03:39 rurban
// added quiet, limit and exclude to FullTextSearch,
// fixed explodePageList with previously unloaded PageList
//
// Revision 1.16 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 1.15 2003/01/18 21:41:01 carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
//
// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
// c-hanging-comment-ender-p: nil
