The default plugin is used for some deprecated rendering of older TWiki versions and of JosWiki. This plugin can also be used to specify some simple custom rendering rules. Note: Create a new TWikiPlugin based on EmptyPlugin if you plan to offer some complex rendering or other functionality.
Plugin settings are stored as preferences variables. To reference
a plugin setting write %<plugin>_<setting>%, for example, %DEFAULTPLUGIN_SHORTDESCRIPTION%
