This patch changes the file to run on both python2 and python3.

The tempfile module has been imported and used.
Although the previous replacement of cmp() by eric works, 
I have replaced cmp(a,b) by ((a>b)-(a<b)) which works correctly.

Thanks!

The version hystory of this patch is:
v1:conversion to py3 by changing the print statements.
v2:add the '__future__' package for compatibility with py2 and py3.
v3:solves the 'version' problem in argparse by adding a new argument.
v4:uses .format() method to make print statements clearer.
v5:updated the shebang and corrected the sequence of import statements.
v6:resent the same with small changes
v7:resent with small changes
v9: replaced os module with tempfile and replaced cmp(a,b)
    with ((a>b)-(a<b)).
