PluginFormat

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.
