title: Is there a tool that allows you to custom build a vcproj?
body: <p>We have several Visual Studio projects, and we would like to:</p>
  
  <ul>
  <li>enable/disable some defines on some of the projects</li>
  <li>add/remove include paths</li>
  <li>change output directories ( lib dependencies ) for libs</li>
  </ul>
  
  <p>In a nutshell, we would like to be able to support all of the things above, without having to have a lot of configurations in the solution file. Is there some tool which allows us to do that, perhaps from command-line, if VS doesn't support such a thing? We are using VS2005 Professional.</p>
