Boost is not a "template metaprogramming" library, as you seem to be implying. It's just a good library that happens to use template techniques for some purposes for which it is very well suited, for example, the Spirit parser.

You don't need to know template metaprogramming at all to use Spirit. In fact, what Spirit does is make the specification of parsers look like BNF but in C++ syntax. Internally, yeah, the library is awfully complex. But that is the point of a library - it implements once and for all difficult things so that library user's lives are easier. And boost achieves that goal nicely.
