title: s3cmd get an entire directory
body: <p>I have a directory in my s3 that has only another directory inside it, but I don't know it's name. Using command line "get" tools, i'd like to download that directory, but it doesn't seems to want to.</p>
  
  <p>The structure looks like:
  <code>
  my-production/top-dir/sub-dir/some-files.jpg
  </code>
  then
  <code>
  s3cmd get  s3://my-production/top-dir/* local-dir
  </code></p>
  
  <p>The "sub-dir" directory does not download. 
  Do I have to get the directory name, make the directory locally, then "get" all it's contents?</p>
