Wave is a library, which exposes an iterator, which in turn returns
preprocessed C/C++ tokens. 

The Wave application is in fact a very thin driver program, which takes
the command line arguments, instantiates and initializes the iterator(s)
and puts out the string representation of the tokens it gets from the
iterator.

IMHO such a preprocessing C/C++ lexer may be intersting not only for the
Wave application itself, but for others too.

Yeah, I thought of this too. But this would contradict the Spirit
Development plans to separate the Spirit library from its applications
to ease overall maintenance.

I'd like the idea mentioned by Martin Wille to combine 1) and 2).
Thoughts?
