	Important
	To be able to use containers of movable-only values you will need to use containers supporting move semantics, like Boost.Container containers

	Note
	Tested compilers: MSVC-7.1, 8.0, 9.0, GCC 4.3-MinGW in C++03 and C++0x modes, Intel 10.1

What is Boost.Move?

Rvalue references are a major C++0x feature, enabling move semantics for C++ values. However, we don't need C++0x compilers to take advantage of move semanatics. Boost.Move emulates C++0x move semantics in C++03 compilers and allows writing portable code that works optimally in C++03 and C++0x compilers.
