It is recommended that [[Plugins]]  start with some standard information in TiddlerSlicing format. For example, see the ExamplePlugin:
{{{
|''Name:''|ExamplePlugin|
|''Description:''|To demonstrate how to write TiddlyWiki plugins|
|''Version:''|2.0.2|
|''Date:''|Jul 12, 2006|
|''Source:''|http://www.tiddlywiki.com/#ExamplePlugin|
|''Author:''|JeremyRuston (jeremy (at) osmosoft (dot) com)|
|''License:''|[[BSD open source license]]|
|''~CoreVersion:''|2.1.0|
|''Browser:''|Firefox 1.0.4+; Firefox 1.5; InternetExplorer 6.0|
}}}
At the moment, only ~CoreVersion affects how [[Plugins]] are processed: if the ~CoreVersion is specified for a plugin, TiddlyWiki will only execute the plugin if the core code version matches or exceeds the version specified. For example, if you specify a ~CoreVersion of 2.2, version 2.1.x of TiddlyWiki will refuse to execute the plugin.

To indicate an error, plugins should just {{{throw}}} an exception. The text of the exception will be displayed in the PluginManager.
