They're very much libraries, not a framework, so you can easily ignore
large parts. (Wave and spirit, for example.)

Also, of particular interest might be the Boost Pointer Containers
library.  A boost::ptr_vector<T> is internally a std::vector<T*>, so
it doesn't need copy constructability or assignability of A, with a
helpful interface that calls delete on the pointers before erasing
them from the container and has most of the interface look like a
sequence of T, so you don't need to add extra indirections to
iterators and such.
