title: msbuild fileupdate setup project
body: <p>I'm looking to use the fileUpdate task from msbuildtasks.tigris.org to modify image src's as part of our web setup project so that they will point to a static img sub domain (or later a CDN)<br>
  I can run a task within a given project with:</p>
  
  <pre><code>&lt;Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" /&gt;
  &lt;Target Name="AfterBuild"&gt;
  &lt;FileUpdate 
     Files="basic.css" 
     Regex="/images/([^\)]*)" 
     ReplacementText="http://img.domain.com/images/$1" /&gt;
  &lt;/Target&gt;
  </code></pre>
  
  <p>However, I dont want to overwrite the original css source file, but want to run this as part of our deployment project that produces an msi.
  This is done using a web setup project (.vdproj) which also uses a custom actions project which is just a standard .csproj</p>
  
  <p>My questions are:  </p>
  
  <ol>
  <li>How can I run this task in the setup project so that I replace content in the files that go into the .msi?  </li>
  <li>Is there a way to use wildcards for the files - ideally I want to say do this for ALL .css files?</li>
  </ol>
