title: How to extract and read a bzip2ed hdf5 file in Python?
body: <p>everything is in the question. </p>
  
  <p>I use pytables to treat hdf5 files. When I receive a hdf5.bz2 file I can treat it if I uncompress it first in my file manager. </p>
  
  <p>I don't find a proper way to extract my hdf5 file from a hdf5.bz2 file with python, can someone give me a hint?</p>
  
  <p>Is there a way to do it directly with the instruction </p>
  
  <pre><code>tables.open_file(hdf5.bz2) 
  </code></pre>
  
  <p>adding some parameters?</p>
  
  <p>Thanks a lot</p>
