// stabilize on numeric keys (strange php problem)
//
// Revision 1.22 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 1.21 2003/02/21 04:22:28 dairiki
// Make this work for array-valued data. Make display of cached markup
// readable. Some code cleanups. (This still needs more work.)

// Revision 1.20 2003/01/18 21:19:24 carstenklapp
// Code cleanup:
// Reformatting; added copyleft, getVersion, getDescription

// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
