To check the md5_ checksum of a file:

  - Linux:
  
  .. code-block:: sh
  
     md5sum <filename>
     
  - Mac OS X:
  
  .. code-block:: sh
  
     md5 <filename>
     
  - Windows :
  
    1. save this ``md5sum.py`` file:
    
       .. code-block:: python
       
          import sys
          import os
          import md5

          if len(sys.argv) == 1:
              print 'Usage: %s <filename>' % os.path.basename(sys.argv[0])
          else:
              print md5.md5(file(sys.argv[1]).read()).hexdigest() 
              
    2. launch:
    
       .. code-block:: sh
       
          python md5sum.py <filename>
