Maybe an example will help.  Referring back to the equation in the PDF 
program description will also help.

In the gettysburg.txt file the word "are" appears three times.  It 
appears on lines 3, 5, and 6.

lets call these $\alpha_0$, $\alpha_1$, and $\alpha_2$.  If I sum these 
up I get 14.

I then divide this number by the total number of occurrences ($\gamma$, 
which is 3), and get 4.6667

I then divide this by the total number of lines in the document ($N$, 
which is 25).  That gives me
the number .18667.   Multiply that by 100 to get the final word 
distrubution index (18.667).


That is now telling you that those words, on average, fell within the 
first 18.667% of the document.

Does that clear things up?
