title: Typoscript use constant in include_typoscript
body: <p>Can we use constant variable in include_typoscript</p>
  
  <p>In my constants.txt file</p>
  
  <pre><code>filepaths{
      # cat=FLUIDPAGES/settings; type=text; label=Pfad zu den Templates
      defaultTemplateRootPath = typo3conf/ext/defaulttemplate/
  }
  </code></pre>
  
  <p>In my setup.txt file</p>
  
  <pre><code>Include Page Template
  &lt;INCLUDE_TYPOSCRIPT: source="FILE: {$filepaths.defaultTemplateRootPath}fluid.txt"&gt;
  </code></pre>
  
  <p>I just need to use {$filepaths.defaultTemplateRootPath} in my setup file for include typoscript file, If yes it's very helpful for me and I could add multiple themes/templates in multi - Domain site.</p>
