I am trying to write a program that will re-order a file so that the 
paragraphs are lined up.  Then I can just run diff on the result.

So for instance if I had 2 text files, each with 3 paragraphs:

Text File 1
-----------------
abc 123

I am in cyberspace

this is a text file


Text File 2
----------------
this is a text file

abc 134

I am in cyberspace


Output
-------------
abc 134

I am in cyberspace

this is a text file



I'd like the program to reorder Text File 2 so I can then run the result 
through diff.  I realize that if the two files are completely different, the 
output will look pretty wacky, but I'm not too worried abouyt that.

Any ideas on how to write such a program?  Does such a utility already exist?
Many many thanks in advance.
Steve
