---++ TopicVarsPlugin TWiki Plugin 

This plugin will allow you to create variables in arbitrary topic pages, and not just WebPreferences. You can then refer to those variables from any topic within the same Web or Wiki. (Perhaps a future iteration will support [[TWiki.InterwikiPlugin][Interwiki]] references, but that's probably not likely, unless we use XML-RPC or something to cut down the overhead of getting those values from afar.)

---+++ Syntax Rules 

   * Set a variable:<br />
      <nop>* Set VARIABLE_NAME = "some value"<br />

   * Use a variable in the same Web:<br />
      %<nop>TopicName.VARIABLE_NAME%

   * Use a variable from a different Web:<br />
      %<nop>Webname.TopicName.VARIABLE_NAME%


(setting values is done just like in WebPreferences; with six preceeding spaces, an asterisk, and so on).

---+++ <nop>%TOPIC% Settings

   * One line description, is shown in the [[TWiki.TextFormattingRules][TextFormattingRules]] topic
   * Set SHORTDESCRIPTION = Set variables in arbitrary topics and refer to them from other topics within the same web

   * Debug %TOPIC% (see output in <code>data/debug.txt</code>)
   * Set DEBUG = 0
