Preferences:

• List of TWiki webs: (the first line of a topic; to add a web see TWikiDocumentation and TWikiWebsTable)
  • Set WIKIWEBLIST = TWiki . { Main | TWiki | Know | Test }

• List of topics of a web: (the second line of a topic, is overwritten by web preferences)

• Site-level preferences that are not allowed to be overridden by WebPreferences and user preferences:
  • Set FINALPREFERENCES = WIKIWEBMASTER, PREVIEWBGIMAGE

Notes:

• A preference is defined as:
  6 spaces * Set NAME = value
  Example:
  • Set WEBBGCOLOR = #FFFFC0
• Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
  • When you write variable %WEBBGCOLOR% , it gets expanded to #FFE0B0 .
• The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
• You can introduce new variables and use them in your topics and templates. There is no need to change the TWiki engine (Perl scripts).
