Hugh-
I recently had to impliment pagination on our site as well, and had to do it 
in the following way:
The following code uses velocity entirely to paginate a list of items.
I should note, however, that I was forced to do it this way because the 
context object that I was looping through was an Array not and ArrayList. An 
ArrayList would have made this easier to do as I could have looped through 
the arraylist and made smaller arrays based on the number of items to show 
per page (ie, 10 arrays of 20 items for 200 total items).  I dont know what 
you are going to be handling in the template, but If it is an arraylist, you 
should check look into the methods and properties of that util.

My script is attached, but, I should say that, given alternatives, its 
pretty hacky.  But if you are stuck using only velcoity to do this, it works 
really well.  Lastly, I expanded on this pagination to include drop down to 
display of all the ranges (1-10, 11-20, 21-30 etc).  I also created a drop 
down which allows users to choose the # of items to show per page (10, 20, 
30, etc).  It works pretty well with a little JS included.  Let me know if 
you want some info on that, but I think this script give enough info to 
figure out the rest.

Peace
Corey
