:Description:
 Join is an asynchronous, message based C++ concurrency
 library based on join calculus. It is applicable both to
 multi-threaded applications and to the orchestration of asynchronous,
 event-based applications. It follows Comega's design and
 implementation and builds with Boost facilities. It provides a high
 level concurrency API with asynchronous methods, synchronous methods,
 and chords which are "join-patterns" defining the synchronization,
 asynchrony, and concurrency.
Pimpl
-----
:Author: Vladimir Batov
:Review Manager: Needed
:Download: https://github.com/boost-vault/Miscellaneous/blob/master/Pimpl.zip
:Description:
 The Pimpl idiom is a simple yet robust technique to minimize
 coupling via the separation of interface and implementation and then
 implementation hiding.  This library provides a convenient yet
 flexible and generic deployment technique for the Pimpl idiom.  It's
 seemingly complete and broadly applicable, yet minimal, simple and
 pleasant to use.
Sorting
-------
:Author: Steven Ross
:Review Manager: Needed
:Download: https://github.com/boost-vault/Sorting
:Description:
 A grouping of 3 templated hybrid radix/comparison-based sorting
 algorithms that provide superior worst-case and average-case
 performance to std::sort: integer_sort, which sorts fixed-size data
 types that support a rightshift (default of >>) and a comparison
 (default of <) operator.   float_sort, which sorts standard
 floating-point numbers by safely casting them to integers.
 string_sort, which sorts variable-length data types, and is optimized
 for 8-bit character strings.
 All 3 algorithms have O(n(k/s + s)) runtime where k is the number of
 bits in the data type and s is a constant, and limited memory overhead
 (in the kB for realistic inputs).   In testing, integer_sort varies
 from 35% faster to 2X as fast as std::sort, depending on processor,
 compiler optimizations, and data distribution.   float_sort is roughly
 70% faster than std::sort.   string_sort is roughly 2X
 as fast as std::sort.
Quaternions, Vectors, Matrices
------------------------------
:Author: Emil Dotchevski
:Review Manager: Needed
:Download: http://www.revergestudios.com/boost-qvm/
:Description:
 QVM defines a set of generic functions and operator overloads for
 working with quaternions, vectors and matrices of static size. The
 library also defines vector and matrix data types, however it allows
 users to introduce their own types by specializing the q_traits,
 v_traits and m_traits templates.
Variadic Macro Data
-------------------
:Author: Edward Diener
:Review Manager: Needed
:Download: `Boost Sandbox <http://svn.boost.org/svn/boost/sandbox/variadic_macro_data/>`__
:Description:
 This library adds support and functionality for variadic macros to
 Boost as well as integrating variadic macros with the Boost PP
 library without changing the latter library in any way.
Block Pointer
-------------
:Author: Phil Bouchard
:Review Manager: Needed
:Download: https://svn.boost.org/svn/boost/sandbox/block_ptr/
:Description:
 Deterministic memory manager of constant complexity capable of
 handling cyclic collections.
Singularity
-----------
:Author: Ben Robinson
:Review Manager: Needed
:Download: https://github.com/cppmaven/Singularity
:Description: The Singularity Design Pattern allows you to restrict
  any class to a single instance. Unlike the infamous Singleton,
  Singularity gives you direct control over the lifetime of the object,
  does not require you to grant global access to the object, nor does it
  limit you to the default constructor for that object.
Extended Complex Numbers
------------------------
:Author: Matthieu Schaller
:Review Manager: Needed
:Download: http://code.google.com/p/cpp-imaginary-numbers/
:Description:
 The library is an extension of the std::complex class addressing two issues:
 1.  The standard does not guaranty the behaviour of the complex class if 
     instantiated with types other than float/double/long double.
 2.  Some calculation where pure imaginary numbers (i.e. multiples of
     sqrt(-1)) appear are unnecessarily slowed down due to the lack of
     support for these numbers.  The code I submit contains two
     interleaved classes boost::complex and boost::imaginary which can
     be instantiated with any type T provided T overloads the usual
     arithmetic operators and some basic (real) mathematical functions
     depending on which complex function will be used.  It is thus an
     extended version of Thorsten Ottosen's n1869 proposal
     (http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1869.html)
Metaparse
---------
:Author: Abel Sinkovics
:Review Manager: Needed
:Download: http://abel.web.elte.hu/metaparse/metaparse.zip
:Description:
 Metaparse is a library for constructing parsers parsing at
 compile-time based on template metaprogramming. The parsers built with
 the library take boost::mpl::strings as input and can produce
 - types
 - objects (types with public static members)
 - callable C++ functions (types with public static method)
 - template metafunction classes
 as output (based on the input being parsed).
 On compilers supporting constexpr the library provides the following
 syntactic sugar for writing the input of the parsers:
 BOOST_STRING("this is a string")
 The library can be used for implementing DSLs in C++, including DSLs
 making C++ template metaprogramming easier (see examples).
Polygon: Voronoi Extensions
---------------------------
:Author: Andril Sydorchuk
:Review Manager: Lucanus Simonson
:Download: http://svn.boost.org/svn/boost/sandbox/gtl/
:Description:
 This library extends Boost.Polygon with the following features:
 - Robust and efficient implementation of the sweepline algorithm that
 allows to construct Voronoi diagram, Delaunay triangulation and medial axis
 of a set of points and line segments.
 - Coordinates of the output geometries are computed within the 64 machine
 epsilon relative error (6 mantissa bits).
 - Voronoi diagram data structure that allows efficient traversal and data
 association with the output Voronoi graph.
 - No 3rd party dependencies (e.g. GMP, MPFR), all the required multiple
 precision types are implemented as part of the library.
 - The input and output coordinate type domains are configurable via
 coordinate type traits, thus allowing to compute coordinates of the Voronoi
 vertices within any required precision.
 - The full construction of the Voronoi diagram of 100 000 points takes only
 0.27 seconds (see benchmarks).

:Review Manager: Dave Abrahams
:Download: http://sourceforge.net/projects/contractpp/files/latest/download
:Description:
 This library implements Contract Programming for the C++ programming
 language (see the end of this email). In addition, the library
 implements virtual specifiers (final, override, and new, see C++11),
 concept checking, and named parameters.
 This library is implemented for the C++03 standard and it does not
 require C++11.
Nowide
------
:Author: Artyom Beilis
:Review Manager: Needed
:Download: http://cppcms.com/files/nowide/
:Description:
 This library makes cross platform Unicode aware programming easier.
 It provides an implementation of standard C and C++ library functions,
 such that their inputs are UTF-8 aware on Windows without requiring to
 use Wide API.
ODEint
------
:Author: Karsten Ahnert and Mario Mulansky
:Review Manager: Needed
:Download: https://github.com/headmyshoulder/odeint-v2
:Description:
 odeint provides routines for numerically solving Ordinary Differential
 Equations, a task heavily required when approaching scientific problems
 numerically. In odeint we have implemented the most common algorithms in
 a modern, generic way which provides several advantages over existing
 implementations. The main focus of odeint is to separate algorithms from
 the underlying basic computation unit. This allows for example to easily
 use the power of modern GPUs via CUDA or OpenCL to speed up
 computational heavy simulations.
