## Introduction

| Important
This library is deprecated in favor of native C++11 standard library features, as a result it receives little or no maintenance.

The TR1 library provides an implementation of the C++ Technical Report on Standard Library Extensions. This library does not itself implement the TR1 components, rather it's a thin wrapper that will include your standard library's TR1 implementation (if it has one), otherwise it will include the Boost Library equivalents, and import them into namespace `std::tr1`.
