I am using it for some time and hope that other will benefite from it. One file streamline.h will help user to stream out/in an arbitrary item of primitives or STL containers of them. It is very simple to use; just type like this: #include "streamline.h" using namespace hekate; ....... typedef std::pair<std::string, std::vector<int> > element; element one,other; And stream it out as: streamline(cout,one); or stream it in as: streamline(cin,other); . User will find a lot of examples in the streamtest.cpp file at streamline.tar in "Files section". The streaming templates were tested with gcc version 3.3.2, msvc7 and ibm89 c++ compiler.
