Yes, please accept it.

It's OK.

Fine. I liked the attempts to minimize extra space per object. I
didn't like that there were neither tests nor conventional examples.
The file where the Quickbook docs took its code examples was the only
*.cpp file provided. Fortunately, it's (intentionally) compilable.

It's extensive, both the usage (Quickbook) and code (Doxygen) guides.

On the usage guide, I don't think the tutorial's "ignore" type does
what you think it does.

I find restrained types to be useful.

Yes, with Mac OS X 10.4 (PowerPC) using XCode. No problems.

A day of reading and trying out the examples.
