// 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 1.8 2004/10/14 19:19:34 rurban
// loadsave: check if the dumped file will be accessible from outside.

//

// plugin-list support for pages and exclude args
//
// Revision 1.4 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 1.3 2004/06/28 18:58:18 rurban
// fixed another pass-by-reference
//
// Revision 1.2 2004/06/18 14:42:17 rurban
