title: Where is set the active build configuration in Xcode 4
body: <p>I have 3 configurations in my project (Debug, Distribution_AdHoc and Distribution_AppStore). In Xcode 3 we had a list to choose device, version, configuration and target before build and run. Now with Xcode 4 we only have the device kind and version in this list. This bring my two questions:</p>
  
  <ol>
  <li><p>So where is defined the configuration used ? Is that the configuration defined in "Project > Info > Command-line builds use: Debug" ?</p></li>
  <li><p>And now the "Project" menu is replaced by "Product" So where can we create (or duplicate and edit) a Configuration ?</p></li>
  </ol>
  
  <p>Thank you.</p>
