**_Preferences:_**

* List of %WIKITOOLNAME% webs: (the first line of a topic; to add a web see [[TWikiDocumentation]] and [[TWikiWebsTable]])
  * Set WIKIWEBLIST = [%WIKITOOLNAME%](%WIKIHOMEURL%) . \{ [Main](%SCRIPTURLPATH%/view%SCRIPTSUFFIX%/%MAINWEB%/WebHome) | [TWiki](%SCRIPTURLPATH%/view%SCRIPTSUFFIX%/%TWIKIWEB%/WebHome) | [Know](%SCRIPTURLPATH%/view%SCRIPTSUFFIX%/Know/WebHome) | [Test](%SCRIPTURLPATH%/view%SCRIPTSUFFIX%/Test/WebHome) \}

  * Set FINALPREFERENCES = WIKIWEBMASTER, PREVIEWBGIMAGE

**_Notes:_**

* A preference is defined as: <br />`6 spaces * Set NAME = value`<br /> Example:
  * Set WEBBGCOLOR = #FFFFC0
* Preferences are used as %TWIKIWEB%.TWikiVariables by enclosing the name in percent signs. Example:
  * When you write variable <code>%WEBBGCOLOR%</code> , it gets expanded to `%WEBBGCOLOR%` .
* The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set <code>WEBCOPYRIGHT</code> before <code>WIKIWEBMASTER</code> since <code>%WEBCOPYRIGHT%</code> uses the <code>%WIKIWEBMASTER%</code> variable.
* You can introduce new variables and use them in your topics and templates. There is no need to change the %WIKITOOLNAME% engine (Perl scripts).
