Variable declaration programming style and the auto keyword

[Jeremy DeHaan]

I've seen a lot of code lately that uses the auto keyword when 
declaring variables, but for some reason I don't really care much 
for it.

I'd like to make tutorials for a library I am working on, but I 
want to use "D style." Does such a style exist? Is auto generally 
preferred when declaring variables?

How often does everyone here use it?

Thanks much!
