PDF docs for LocalFunction, ScopeExit, Functional/OverloadedFunction, and Utility/IdentityType looks good. A very minor thing is that the graph images for LocalFunction are cut because they are too big and go out of page width (see pages 38-40) -- there's probably nothing that can be done about that.
I've just changed the images DPI to 300dpi - this doesn't change html browser views (checked on IE, Firefox and Opera) - but does alter PDF rendering. I haven't rebuilt the whole PDF build, but I've placed the updated local_function.pdf here: https://docs.google.com/open?id=0B9xLRWKoNSvKc05JSV9fQzlyV1k
BTW, which command did you use to generate the PDF? bjam pdf? They look really good and I'd like to be able to generate them for some of my internal project that use qbk documentation.
Yes "bjam pdf": you will need an FO processor configured in your user-config.jam (either XEP or Apache FOP). John.
