// $Log: PrevNext.php,v $
// Revision 1.4 2004/06/14 11:31:39 rurban
// renamed global $Theme to $WikiTheme (gforge nameclash)
// inherit PageList default options from PageList
// default sortby=pagename
// use options in PageList_Selectable (limit, sortby, ...)
// added action revert, with button at action=diff
// added option regex to WikiAdminSearchReplace
//
// Revision 1.3 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 1.2 2003/01/18 22:01:43 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
// indent-tabs-mode: nil
// End:
