title: Flatten some directories but not others automatically?
body: <p>I have a directory with several thousand subdirectories inside (no subdirectories within those subdirectories however), and I need to flatten the contents of only some of the subdirectories, so basically bringing the contents of those directories to the root directory.</p>
  
  <p>But I can't do that with all the subdirectories, and the ones which I can't flatten have multiple files in them.</p>
  
  <p>Any way to do this automatically? Python script, perl script, bash, or whatever? I really, really, really don't want to have to do this by hand...</p>
