title: Why does Delphi (dcc32.exe) have an option to set a "Namespace search path"?
body: <p>The compiler (dcc32.exe) in Delphi 2007 and higher has an option</p>
  <pre><code>-NS&lt;namespaces&gt; = Namespace search path
  </code></pre>
  <p>Is this releated to the compiler options 'Default namespace' and 'Namespace prefixes' in the project options dialog? Search 'path' sounds like a folder (directory) name, so I am not sure what this option is good for.</p>
