[Boost-users] STL Maps

hi, i'm using stl maps in my project to create maps. this stl maps is datatype specific. eg map<int,int>, map <string,int>, etc.. is they any way to create a template map like map<T,T>. so that the map is compatible across any datatype being passed to it? is it possible to do in boost library by using property map concept? thanx, merlin.
