title: gclient runhooks fails
body: <p>I'm trying to build Chrome under windows, I got the chromium trunk using tortoiseSVN and I believe I got everything correctly, but when I run "gclient runhooks" I get the error: "Error: client not configured; see 'gclient config'".</p>
  
  <p>Now, I know that it happens because I don't have a ".gclient" file on the same directory, but I couldn't find .gclient file anywhere in the project. I tried to create .gclient file myself but it says there's a solution missing.</p>
  
  <p>I'm probably missing something, can anyone help me with that? I'm pretty stuck!
  Thanks!</p>
