Well read on and see :-)

And that's the first, more visible part of templates, a bit like
generics in Java.
Template are incomplete pieces of code with left-empty 'slots' which
you can fill at compile-time to decide what code will be compiled.
You can generate entire functions / class hierarchies or nicely
crafted-for-your-need code / pre-computed-by-the-compiler code with
templates.
