What is Boost.Move?

Introduction

Containers and move semantics

Constructor Forwarding

Implicit Move when returning a local object

Move iterators

Move inserters

Move algorithms

Emulation limitations

Initializing base classes
Template parameters for perfect forwarding
Binding of rvalue references to lvalues
Assignment operator in classes derived from or holding copyable and movable types
Templated assignment operator in copyable and movable types

	Important
	To be able to use containers of movable-only values in C++03 mode you will need to use containers supporting move semantics, like Boost.Container containers

Tested compilers

Boost.Move has been tested in the following compilers/platforms:

Visual C++ >= 7.1.
GCC >= 4.1.

	Warning
	GCC < 4.3 and MSVC < 9.0 are deprecated and will be removed in the next version.
