title: Is there a tool to diff/merge/sort localizable strings files?
body: <p>Localizable strings file which are used for Apple/iPhone apps localization have the following format:</p>
  
  <pre>/* COMMENT */
  "KEY" = "VALUE"</pre>
  
  <p>Note that <strong><em>KEY</em></strong> is unique in a given <strong>strings</strong> file.<br>
  <strong><em>COMMENT</em></strong> is optional however it can help the translator with some additional info.</p>
  
  <p>Example:</p>
  
  <pre>
  /* Menu item to make the current document plain text */
  "Make Plain Text" = "Make Plain Text";
  /* Menu item to make the current document rich text */
  "Make Rich Text" = "Make Rich Text";</pre>
  
  <p>I would like to diff/merge two strings files and optionally sort that kind of files.
  It would be great if the comments would be kept while doing these operations.</p>
  
  <p>The format is quite simple and I could write let's say a python script to do that, but if somebody has already done that, I prefer not reinventing the wheel ;)</p>
  
  <p>Do you know a tool that can manipulate strings file?</p>
