00002 // A supermacro to generate some partial template specializations for
00003 // s11n-proxying class templates taking two parameterized types. Works
00004 // with std::map and std::pair-like types, with the appropriate
00005 // proxies. See the various proxy files, like std/map.hpp and
00006 // std/pair.hpp, for how to use it.
00007 //
00008 // Achtung: only suitable for monomorphic or base-most template types.
