title: Reduce how much xcodebuild writes to command-line
body: <p>I have a simple script that runs xcodebuild for a C++ project. However it prints out a huge amount of output for each file compiled, 10-20 lines, which makes it impossible to read easily. Ideally I'd jut like to see a list of the files compiled, one per line.</p>
  
  <p>I'm not a nix guy but it seems like nix command-line can do pretty much anything... is there a neat way to do this? xcodebuild itself doesn't seem to have any control options for verbosity.</p>
