+Xavi, Ashish.
hi Serkan,
       At the moment there is no tool which does this. We can write one, 
which will do the reconstruction. What are the requirements? When would 
you like to use it? Why do you not want the gluster processes to run? 
Should the tool connect to the machines on which the fragments are 
stored and then construct the file and write it somewhere or will all 
the chunks be copied somewhere and we run the tool locally?

Answers to these questions should help us come up with a good problem 
statement which we can find a solution for.
