title: tf.exe errors out with MSB3073: exited with code 1 while doing a label /recursive - diagnostic advice?
body: <p>I'm working with a VS 2008 project file as the build script... when it gets to:
  TF.exe label Build_01_29_1$/RootDirectory/ChildDirectory . /recursive
  It errors out right away (no time out issues that I could fined)
  All I get is that is "exited with code 1" and error:MSB3073 and nothing else descriptive.</p>
  
  <p>So any advice on how to diagnosis this further? Or anybody run into it before?</p>
