1. Introduction: 
----------------

This program is a component of the bigram Statistics Package that sort 
one bigram count file.
The scripts and files provided here could be used to test the correct 
behavior of the program and backward compatibility. 

2. Tests:
----------

2.1 Normal conditions:
----------------------

Tests written in testA*.sh test huge-count.pl under normal conditions.
Run normal-op.sh to run all test cases testA*.sh 

Test A1:
Test A2:	Tests on general bigram files
Test A3: 	Tests on repeated bigrams 


2.2 Error conditions:
----------------------

Tests written in testB*.sh test huge-sort.pl under error conditions.
Run error-op.sh to run all test cases testB*.sh

Test B1:	Tests when the bigram file is incorrectly formatted
		The file is already sorted and count the frequency.

3. Conclusions:
---------------

We have tested program huge-combine.pl enough to conclude that it runs 
correctly. We have also provided the test scripts so that future versions of 
huge-sort.pl can be compared to the current version against these scripts.
