title: force doxygen to pick one from versioned files
body: <p>Just started using doxygen today. How would you go about this.</p>
  
  <p>Given following dir structure</p>
  
  <pre><code>-rootDir
      -dirA
          -dirAFile_ver01
          -dirAFile_ver02
          -dirAFile_ver03
          -dirAFile_ver04
      -dirB
          -dirBFile_ver01
          -dirBFile_ver02
          -dirBFile_ver03
      -dirC
          -dirCFile_ver01
          -dirCFile_ver02
  </code></pre>
  
  <p>My expectations from doxygen are to take only last version of file from single dir e.g. <code>dirAFile_ver04 from dirA</code>, <code>dirBFile_ver03 from dirB</code> etc. I've read about <strong>FILE_VERSION_FILTER</strong> tag, but I'm not able to make it work. Using CMD command for listing last file (sort by name)<br/><code>FILE_VERSION_FILTER = FOR /f %i IN ('dir /o:n /b') DO (set LAST_VER=%i echo %LAST_VER%)</code></p>
  
  <p>Also would it be possible if all those files would lie in single directory?</p>
  
  <pre><code>-rootDir
      -dirAFile_ver01
      -dirAFile_ver02
      -dirAFile_ver03
      -dirAFile_ver04
      -dirBFile_ver01
      -dirBFile_ver02
      -dirBFile_ver03
      -dirCFile_ver01
      -dirCFile_ver02
      -justFile_0.0.1
      -justFile_0.0.2
  </code></pre>
  
  <p>Thanks in advance</p>
