Boost is a collection of C++ libraries. Albeit there are libraries on 
various subjects, what it covers is fairly little when compared to .NET, 
and it isn't as consistent.

Spirit is a LL(k) parser generator where you define the grammar directly 
with C++ expressions, in a way that resembles EBNF syntax.
Phoenix is a mechanism to define lambda functions with very concise syntax.
Fusion is a set of algorithms that operate on tuples.

Spirit uses Fusion in its data structures and you may use Phoenix to 
embed actions in the grammar.
