**_Notes:_**

* Preferences variables ( on site-level, web-level and user level ) are defined by bullet lines with this syntax:
  * <code>Set VARIABLENAME = value</code>
* Additional preferences variables can be defined on all three level as needed. Example:
  * <code>Set MYLOGO = %PUBURLPATH%/%MAINWEB%/LogoTopic/logo.gif</code>
