What functionality would you like to have in it?

Documentation is always helpful.

Yeep, that's currently missing :(

If in short:
namespace boost { namespace stacktrace {
class stacktrace {
public:
    BOOST_STATIC_CONSTEXPR std::size_t max_symbol_width = 256;
    typedef boost::array<char, max_symbol_width>  frame_t;

    stacktrace() BOOST_NOEXCEPT;
    stacktrace(const stacktrace& bt) BOOST_NOEXCEPT;
    stacktrace& operator=(const stacktrace& bt) BOOST_NOEXCEPT;
    ~stacktrace() BOOST_NOEXCEPT;

    std::size_t size() const BOOST_NOEXCEPT;
    frame_t operator[](std::size_t frame) const BOOST_NOEXCEPT;
};

template <class CharT, class TraitsT>
std::basic_ostream<CharT, TraitsT>& operator<<(std::basic_ostream<CharT, TraitsT>& os, const stacktrace& bt);
}}

So you can construct stacktraces, copy them and output them to streams:

std::cerr << stacktrace();

I think a library like this could be very useful for practical cross-platform development. 

Are there any means for either inspecting the contents of the trace (e.g. iterating over the frames and extracting things like the function name, offset, source file/line if available, etc.)?

Alternatively, is there any way to control the formatting of the trace when it is inserted into a stream? If not, is the format platform-specific or in some common layout?
