* What is your evaluation of the design? * What is your evaluation of the implementation? Adequate * What is your evaluation of the documentation? Needs a better motivating discussion as to how this library improves upon std::exception. Maybe a "best-practices" section could illustrate a few common scenerios. * What is your evaluation of the potential usefulness of the library? High * Did you try to use the library? With what compiler? Did you have any problems? Compiled fine on my gcc 4.1x compiler. * How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? 2 hours. It took me hardly any time getting up to speed on this library and it works as advertised. * Are you knowledgeable about the problem domain? I'm a long time user of "std::exception". *should this library be approved as a boost library? Count me as a "yes" vote. Thanks to the author.
