So inspired by 
http://programmingpraxis.com/2011/08/05/ninety-nine-bottles-of-beer/ , 
I decided to attempt to generate the lyrics to the 99 bottles of beer 
song. To make it interesting I decided to use Boost MPL to generate the 
lyrics using template metaprogramming.

Here is my attempt.

https://gist.github.com/1130306

It compiles with gcc 4.2 against boost 1.47.

Given that I am pretty inexperienced with MPL I would very much 
appreciate some constructive criticism. I'd specifically like to know 
if the code can be cleaned up to be simpler or to perform better. Also 
I'm not entirely happy with the duplication in the PrintX functors, 
would definitely like to get a better approach here.

Thanks,
