title: What does the Keyword tag mean in a *.vcxproj file?
body: <p>I see the following in many *.vcxproj files</p>
  
  <pre><code>&lt;PropertyGroup Label="Globals"&gt;
    &lt;ProjectGuid&gt;{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}&lt;/ProjectGuid&gt;
    &lt;Keyword&gt;Win32Proj&lt;/Keyword&gt;
    &lt;RootNamespace&gt;yadayada&lt;/RootNamespace&gt;
  &lt;/PropertyGroup&gt;
  </code></pre>
  
  <p>What does the <code>&lt;Keyword&gt;Win32Proj&lt;/Keyword&gt;</code> segment mean? Does it affect any behavior during the build?</p>
  
  <p>In general, where can I find documentation on the tags in a project file?</p>
